Inverse (I)-BAR, also known as the IRSp53/MIM homology Domain (IMD), of Missing In Metastasis; The IMD domain, also called Inverse-Bin/Amphiphysin/Rvs (I-BAR) domain, is a dimerization and lipid-binding module that bends membranes and induces membrane protrusions. Members of this subfamily include missing in metastasis (MIM) or metastasis suppressor 1 (MTSS1), metastasis suppressor 1-like (MTSSL) or ABBA (Actin-Bundling protein with BAIAP2 homology), and similar proteins. They contain an N-terminal IMD and a WASP homology 2 (WH2) actin-binding motif at the C-terminus. MIM was originally identified as a missing transcript from metastatic bladder and prostate cancer cells. It is a scaffold protein that functions in a signaling pathway between the PDGF receptor, Src kinases, and actin assembly. It may also function as a cofactor of the Sonic hedgehog (Shh) transcriptional pathway and may participate in tumor development and progression via this pathway. ABBA regulates actin and plasma membrane dynamics to promote the extension of radial glia, which is important in neuronal migration, axon guidance and neurogenesis. The IMD domain of MIM binds and bundles actin filaments, binds membranes, and interacts with the small GTPase Rac.

IRSp53/MIM homology domain; The N-terminal predicted helical stretch of the insulin receptor tyrosine kinase substrate p53 (IRSp53) is an evolutionary conserved F-actin bundling domain involved in filopodium formation. The domain has been named IMD after the IRSp53 and missing in metastasis (MIM) proteins in which it occurs. Filopodium-inducing IMD activity is regulated by Cdc42 and Rac1 and is SH3-independent.

Inverse (I)-BAR, also known as the IRSp53/MIM homology Domain (IMD), a dimerization module that binds and bends membranes; Inverse (I)-BAR (or IMD) is a member of the Bin/Amphiphysin/Rvs (BAR) domain family. It is a dimerization and lipid-binding module that bends membranes and induces membrane protrusions in the opposite direction compared to classical BAR and F-BAR domains, which produce membrane invaginations. IMD domains are found in Insulin Receptor tyrosine kinase Substrate p53 (IRSp53), Missing in Metastasis (MIM), and Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2-like (BAIAP2L) proteins. These are multi-domain proteins that act as scaffolding proteins and transducers of a variety of signaling pathways that link membrane dynamics and the underlying actin cytoskeleton. Most members contain an N-terminal IMD, an SH3 domain, and a WASP homology 2 (WH2) actin-binding motif at the C-terminus, exccept for MIM which does not carry an SH3 domain. Some members contain additional domains and motifs. The IMD domain binds and bundles actin filaments, binds membranes and produces membrane protrusions, and interacts with the small GTPase Rac.

IRSp53 (Insulin Receptor tyrosine kinase Substrate p53) is also known as BAIAP2 (Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2). It is a scaffolding protein that takes part in many signaling pathways including Cdc42-induced filopodia formation, Rac-mediated lamellipodia extension, and spine morphogenesis. IRSp53 exists as multiple splicing variants that differ mainly at the C-termini. One variant (T-form) is expressed exclusively in human breast cancer cells. The gene encoding IRSp53 is a putative susceptibility gene for Gilles de la Tourette syndrome. IRSp53 contains an N-terminal IMD, a CRIB (Cdc42 and Rac interactive binding motif), an SH3 domain, and a WASP homology 2 (WH2) actin-binding motif at the C-terminus. Its IMD domain binds and bundles actin filaments, binds membranes, and interacts with the small GTPase Rac.

Inverse (I)-BAR, also known as the IRSp53/MIM homology Domain (IMD), of Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2-Like 1; The IMD domain, also called Inverse-Bin/Amphiphysin/Rvs (I-BAR) domain, is a dimerization and lipid-binding module that bends membranes and induces membrane protrusions. BAIAP2L1 (Brain-specific Angiogenesis Inhibitor 1-Associated Protein 2-Like 1) is also known as IRTKS (Insulin Receptor Tyrosine Kinase Substrate). It is widely expressed, serves as a substrate for the insulin receptor, and binds the small GTPase Rac. It plays a role in regulating the actin cytoskeleton and colocalizes with F-actin, cortactin, VASP, and vinculin. BAIAP2L1 expression leads to the formation of short actin bundles, distinct from filopodia-like protrusions induced by the expression of the related protein IRSp53. It contains an N-terminal IMD, an SH3 domain, and a WASP homology 2 (WH2) actin-binding motif at the C-terminus. The IMD domain of BAIAP2L1 binds and bundles actin filaments, and binds the small GTPase Rac.

The Bin/Amphiphysin/Rvs (BAR) domain, a dimerization module that binds membranes and detects membrane curvature; BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions including organelle biogenesis, membrane trafficking or remodeling, and cell division and migration. Mutations in BAR containing proteins have been linked to diseases and their inactivation in cells leads to altered membrane dynamics. A BAR domain with an additional N-terminal amphipathic helix (an N-BAR) can drive membrane curvature. These N-BAR domains are found in amphiphysins and endophilins, among others. BAR domains are also frequently found alongside domains that determine lipid specificity, such as the Pleckstrin Homology (PH) and Phox Homology (PX) domains which are present in beta centaurins (ACAPs and ASAPs) and sorting nexins, respectively. A FES-CIP4 Homology (FCH) domain together with a coiled coil region is called the F-BAR domain and is present in Pombe/Cdc15 homology (PCH) family proteins, which include Fes/Fes tyrosine kinases, PACSIN or syndapin, CIP4-like proteins, and srGAPs, among others. The Inverse (I)-BAR or IRSp53/MIM homology Domain (IMD) is found in multi-domain proteins, such as IRSp53 and MIM, that act as scaffolding proteins and transducers of a variety of signaling pathways that link membrane dynamics and the underlying actin cytoskeleton. BAR domains form dimers that bind to membranes, induce membrane bending and curvature, and may also be involved in protein-protein interactions. The I-BAR domain induces membrane protrusions in the opposite direction compared to classical BAR and F-BAR domains, which produce membrane invaginations. BAR domains that also serve as protein interaction domains include those of arfaptin and OPHN1-like proteins, among others, which bind to Rac and Rho GAP domains, respectively.
