synaptotagmin-like mitochondrial-lipid-binding protein (SMP) domain superfamily; The SMP domain is a lipid transport domain found in phospholipid transfer proteins such as synaptotagmin family proteins, tricalbin (TCB) family proteins, maintenance of mitochondrial morphology protein 1 (MMM1), mitochondrial distribution and morphology protein 12 (MDM12), mitochondrial distribution and morphology protein 34 (MDM34), PDZ domain-containing protein 8 (PDZD8), testis-expressed protein 2 (TEX2), meiotically up-regulated gene 190 protein (Mug190), C2 domain-containing protein 2 (C2CD2) and C2 domain-containing protein 2-like (C2CD2L). The SMP domain belongs to a superfamily of lipid/hydrophobic ligand-binding domains called TULIP (tubular lipid-binding proteins). It adopts a TULIP fold with two alpha helices and a highly curved antiparallel beta sheet forming a cornucopia-like structure.

C2 domain; The C2 domain was first identified in PKC. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

synaptotagmin-like mitochondrial-lipid-binding protein (SMP) domain found in C2 domain-containing protein 2-like (C2CD2L); C2CD2L, also called phospholipid transfer protein C2CD2L, or C2CD2-like, or transmembrane protein 24 (TMEM24), is a lipid-binding protein that transports phosphatidylinositol, the precursor of phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), from its site of synthesis in the endoplasmic reticulum to the cell membrane. It is a Ca2+-regulated component of endoplasmic reticulum (ER)-plasma membrane contacts in mammalian neurons. This model corresponds to the SMP domain of C2CD2L, which may be implicated in lipid transport. Pssm-ID: 439239 Cd Length: 177 Bit Score: 262.33 E-value: 4.14e-84

Synaptotagmin-like, mitochondrial and lipid-binding domain; This is a lipid transport domain found in phospholipid transfer proteins such as C2CD2L-like (also known as TMEM24). The TMEM24-SMP domain is shown to bind glycerolipids with a preference for phosphatidylinositol (PI).The bound PI is then transferred to the plasma membrane (PM) where it is converted to phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2] to replenish pools of this lipid hydrolyzed during glucose-stimulated signaling. PI(4,5)P2 is required for Ca2+-dependent exocytosis hence, the SMP domain of TMEM24 is essential for sustaining the intracellular Ca2+ oscillations that trigger bursts of insulin granule release and hence insulin secretion. The SMP domain belongs to a superfamily of lipid/hydrophobic ligand-binding domains called TULIP for (tubular lipid-binding proteins) it adopts TULIP fold with two alpha helices and a highly curved antiparallel beta sheet forming a cornucopia-like structure.
