Second immunoglobulin (Ig)-like C2-set domain of intercellular cell adhesion molecule 1 ...
112-207 1.57e-51

Second immunoglobulin (Ig)-like C2-set domain of intercellular cell adhesion molecule 1 (ICAM-1), and similar domains; The members here are composed of the second immunoglobulin (Ig)-like domain of intercellular cell adhesion molecule 1 (ICAM-1; also known as domain of cluster of differentiation (CD) 54) and similar proteins. During the inflammation process, these molecules recruit leukocytes onto the vascular endothelium before extravasation to the injured tissues. ICAM-1 may be involved in organ targeted tumor metastasis. The interaction of ICAM-1 with leukocyte function-associated antigen-1 (LFA-1) plays a part in leukocyte-endothelial cell recognition. This group also contains ICAM-2 which also interacts with LFA-1. Transmigration of immature dendritic cells across resting endothelium is dependent on the interaction of ICAM-2 with, yet unidentified, ligand(s) on the dendritic cells. ICAM-1 has five Ig-like domains and ICAM-2 has two. ICAM-1 may also act as host receptor for viruses and parasites. The structures of this group show that the second Ig domain lacks a D strand and thus belonging to the C2-set of the IgSF

28-110 8.25e-48

N-terminal immunoglobulin domain of the intercellular adhesion molecules ICAM-1 (Cluster of Differentiation 54 or CD54); member of the I-set of IgSF domains; The members here are composed of the N-terminal immunoglobulin domain of the intercellular adhesion molecules ICAM-1 (Cluster of Differentiation 54 or CD54). The intercellular adhesion molecules ICAM-1, ICAM-2 (Cluster of Differentiation 102 or CD102) and ICAM-3 (Cluster of Differentiation 50 or CD50) mediate a variety of critical intercellular adhesion events in the immune system through interactions with their counter-receptors, the beta2-integrins LFA-1 (CD11a/CD18), Mac-1 (CD11b/CD18), p150,95 (CD11c/CD18), and CD11d/CD18. The ICAMs are type I transmembrane glycoproteins belonging to the immunoglobulin superfamily (IgSF). The binding of the ICAM family members with the beta2-integrins physically stabilizes interactions between pairs of T and B cells, T cells and antigen-presenting cells (APCs), and brings effector cells such as cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells into close proximity to their target cells. All three ICAMs share a common polypeptide homology and structural motif, and the ability to bind LFA-1. The distinct functional role of each ICAM is affected by their relative affinities for LFA-1 (ICAM-1 > ICAM-2 > ICAM-3). ICAM-1 is expressed in most tissues at low levels, and expression is increased by inflammatory cytokines. In contrast, ICAM-2 is expressed predominantly on endothelium and leukocytes (except neutrophils), and its expression generally is not responsive to cytokines. ICAM-3 is expressed on leukocytes and Langerhans cells, but not on resting, cytokine-induced endothelium, or nonhematopoietic tissues.

419-474 3.70e-03

Fourth immunoglobulin domain of the Drosophila melanogaster Dscam protein, and similar domains; a member of the I-set of IgSF domains; The members here are composed of the fourth immunoglobulin domain of the Drosophila melanogaster Down syndrome cell adhesion molecule (DSCAM) protein and similar proteins. Down syndrome cell adhesion molecule (DSCAM) is a cell adhesion molecule that plays critical roles in neural development, including axon guidance and branching, axon target recognition, self-avoidance and synaptic formation. DSCAM belongs to the immunoglobulin superfamily and contributes to defects in the central nervous system in Down syndrome patients. Vertebrate DSCAMs differ from Drosophila Dscam1 in that they lack the extensive alternative splicing that occurs in the insect gene. Drosophila melanogaster Dscam has 38,016 isoforms generated by the alternative splicing of four variable exon clusters, which allows every neuron in the fly to display a distinctive set of Dscam proteins on its cell surface. Drosophila Dscam1 is a cell-surface protein that plays important roles in neural development and axon tiling of neurons. It is shown that thousands of isoforms bind themselves through specific homophilic (self-binding) interactions, a process which mediates cellular self-recognition. Drosophila Dscam2 is also alternatively spliced and plays a key role in the development of two visual system neurons, monopolar cells L1 and L2. This group is a member of the I-set Ig domains, having A-B-E-D strands in one beta-sheet and A'-G-F-C-C' in the other. Like the V-set Ig domains, members of the I-set have a discontinuous A strand but lack a C" strand.

N-terminal immunoglobulin domain of the intercellular adhesion molecules ICAM-1 (Cluster of Differentiation 54 or CD54), ICAM-2 (CD102) and ICAM-3 (CD50); members of the I-set of IgSF domains; The members here are composed of the immunoglobulin (Ig) domain found in the N-terminus of the intercellular adhesion molecules ICAM-1 (Cluster of Differentiation 54 or CD54), ICAM-2 (CD102), and ICAM-3 (CD50). ICAM-1, ICAM-2, and ICAM-3 mediate a variety of critical intercellular adhesion events in the immune system through interactions with their counter-receptors, the beta2-integrins LFA-1 (CD11a/CD18), Mac-1 (CD11b/CD18), p150,95 (CD11c/CD18), and CD11d/CD18. The ICAMs are type I transmembrane glycoproteins belonging to the immunoglobulin superfamily (IgSF). The binding of the ICAM family members with the beta2-integrins physically stabilizes interactions between pairs of T and B cells, T cells and antigen-presenting cells (APCs), and brings effector cells such as cytotoxic T lymphocytes (CTLs) and natural killer (NK) cells into close proximity to their target cells. All three ICAMs share a common polypeptide homology and structural motif, and the ability to bind LFA-1. The distinct functional role of each ICAM is affected by their relative affinities for LFA-1 (ICAM-1 > ICAM-2 > ICAM-3). ICAM-1 is expressed in most tissues at low levels, and expression is increased by inflammatory cytokines. In contrast, ICAM-2 is expressed predominantly on endothelium and leukocytes (except neutrophils), and its expression generally is not responsive to cytokines. ICAM-3 is expressed on leukocytes and Langerhans cells, but not on resting, cytokine-induced endothelium, or nonhematopoietic tissues.

Fourth immunoglobulin domain of the Drosophila melanogaster Dscam protein, and similar domains; a member of the I-set of IgSF domains; The members here are composed of the fourth immunoglobulin domain of the Drosophila melanogaster Down syndrome cell adhesion molecule (DSCAM) protein and similar proteins. Down syndrome cell adhesion molecule (DSCAM) is a cell adhesion molecule that plays critical roles in neural development, including axon guidance and branching, axon target recognition, self-avoidance and synaptic formation. DSCAM belongs to the immunoglobulin superfamily and contributes to defects in the central nervous system in Down syndrome patients. Vertebrate DSCAMs differ from Drosophila Dscam1 in that they lack the extensive alternative splicing that occurs in the insect gene. Drosophila melanogaster Dscam has 38,016 isoforms generated by the alternative splicing of four variable exon clusters, which allows every neuron in the fly to display a distinctive set of Dscam proteins on its cell surface. Drosophila Dscam1 is a cell-surface protein that plays important roles in neural development and axon tiling of neurons. It is shown that thousands of isoforms bind themselves through specific homophilic (self-binding) interactions, a process which mediates cellular self-recognition. Drosophila Dscam2 is also alternatively spliced and plays a key role in the development of two visual system neurons, monopolar cells L1 and L2. This group is a member of the I-set Ig domains, having A-B-E-D strands in one beta-sheet and A'-G-F-C-C' in the other. Like the V-set Ig domains, members of the I-set have a discontinuous A strand but lack a C" strand.

419-474 9.10e-03

Fifth Ig-like domain of Roundabout (Robo) homolog 1/2, and similar domains; a member of the I-set of IgSF domains; The members here are composed of the fifth Ig-like domain of Roundabout (Robo) homolog 1/2 and similar domains. Robo receptors play a role in the development of the central nervous system (CNS), and are receptors of Slit protein. Slit is a repellant secreted by the neural cells in the midline. Slit acts through Robo to prevent most neurons from crossing the midline from either side. Three mammalian Robo homologs (Robo1, -2, and -3), and three mammalian Slit homologs (Slit-1,-2, -3), have been identified. Commissural axons, which cross the midline, express low levels of Robo; longitudinal axons, which avoid the midline, express high levels of Robo. Robo1, -2, and -3 are expressed by commissural neurons in the vertebrate spinal cord and Slits 1, -2, -3 are expressed at the ventral midline. Robo-3 is a divergent member of the Robo family which instead of being a positive regulator of slit responsiveness, antagonizes slit responsiveness in precrossing axons. The Slit-Robo interaction is mediated by the second leucine-rich repeat (LRR) domain of Slit and the two N-terminal Ig domains of Robo, Ig1 and Ig2. The primary Robo binding site for Slit2 has been shown by surface plasmon resonance experiments and mutational analysis to be is the Ig1 domain, while the Ig2 domain has been proposed to harbor a weak secondary binding site. The fifth Ig-like domain of Robo 1 and 2 is a member of the I-set Ig domains, having A-B-E-D strands in one beta-sheet and A'-G-F-C-C' in the other. Like the V-set Ig domains, members of the I-set have a discontinuous A strand but lack a C" strand. I-set domains are found in several cell adhesion molecules (such as VCAM, ICAM, and MADCAM), and are also present in numerous other diverse protein families, including several tyrosine-protein kinase receptors
