 823-1100 1.72e-84

synaptotagmin-like mitochondrial-lipid-binding protein (SMP) domain found in testis-expressed protein 2 (TEX2) and similar proteins; testis-expressed protein 2 (TEX2), also called transmembrane protein 96 (TMEM96), is a transmembrane protein with uncharacterized biological function. Diseases associated with TEX2 include Wernicke-Korsakoff Syndrome. This model corresponds to the SMP domain of TEX2, which may be implicated in lipid transport.

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.

 823-914 6.65e-04

synaptotagmin-like mitochondrial-lipid-binding protein (SMP) domain found in maintenance of mitochondrial morphology protein 1 (Mmm1) and similar proteins; Maintenance of mitochondrial morphology protein 1 (Mmm1), also called mitochondrial outer membrane protein Mmm1, or yeast mitochondrial escape protein 6 (YME6), is a mitochondrial outer membrane protein essential for establishing and maintaining the structure of mitochondria and maintenance of mtDNA nucleoids. It is a component of the ER-mitochondrion encounter structure/ mitochondrial distribution and morphology (ERMES/Mdm) complex, which serves as a molecular tether to connect the endoplasmic reticulum and mitochondria. Components of this complex are involved in the control of mitochondrial shape and protein biogenesis, and function in nonvesicular lipid trafficking between the ER and mitochondria. The Mdm12-Mmm1 subcomplex functions in the major beta-barrel assembly pathway that is responsible for biogenesis of all outer membrane beta-barrel proteins, and acts in a late step after the SAM complex. The Mdm10-Mdm12-Mmm1 subcomplex further acts in the TOM40-specific pathway after the action of the Mdm12-Mmm1 complex. This model corresponds to the SMP domain of Mmm1, which may be implicated in lipid transport.

 823-914 7.29e-04

synaptotagmin-like mitochondrial-lipid-binding protein (SMP) domain of the extended synaptotagmin (E-Syt) family; The extended synaptotagmin (E-Syt) family includes a group of Ca2+-regulated intrinsic membrane proteins, such as E-Syt1, E-Syt2 and E-Syt3. They are composed of an N-terminal endoplasmic reticulum (ER)-membrane anchor, a central SMP-domain, and five (E-Syt1) or three C-terminal cytoplasmic C2-domains (E-Syt2 and E-Syt3). The ER-membrane anchor and C2 domains are required for tethering, while the SMP domain is a lipid-binding domain that links the ER with other lipid bilayer-membranes within the cell. This model corresponds to the SMP domain, which has a beta-barrel structure like protein modules in the tubular-lipid-binding (TULIP) superfamily. It dimerizes to form an approximately 90-Angstrom-long cylinder traversed by a channel lined entirely with hydrophobic residues. The following two C2 domains then form arched structures flexibly linked to the SMP domain.
