Domain Architecture (Details)
InterPro domains assigned to SynO:
Ca2+ ions are unique in that they not only carry charge but they are also the most widely used of diffusible second messengers. Voltage-dependent Ca2+ channels (VDCC) are a family of molecules that allow cells to couple electrical activity to intracellular Ca2+ signalling. The opening and closing of these channels by depolarizing stimuli.uch as action potentials.llows Ca2+ ions to enter neurons down a steep electrochemical gradient.roducing transient intracellular Ca2+ signals. Many of the processes that occur in neurons.ncluding transmitter release.ene transcription and metabolism are controlled by Ca2+ influx occurring simultaneously at different cellular locales. The activity of this pore is modulated by 4 tightly-coupled subunits: an intracellular beta subunit; a transmembrane gammasubunit; and a disulphide-linked complex of alpha-2 and delta subunits.hich are proteolytically cleaved from the same gene product. Voltage-gated calcium channels are classified as T.... and R.nd are distinguished by their sensitivity to pharmacological blocks.ingle-channel conductance kinetics.nd voltage-dependence. On the basis of their voltage activation properties.he voltage-gated calcium classes can be further divided into two broad groups: the low (T-type) and high (L... and R-type) threshold-activated channels .The voltage-dependent calcium channel gamma (VDCCG) subunit family consistsof at least 8 members.hich share a number of common structural features. Each member is predicted to possess 4 transmembrane domains.ith intracellularN- and C-termini. The first extracellular loop contains a highly conservedN-glycosylation site and a pair of conserved cysteine residues. TheC-terminal 7 residues of VDCCG-2.3.4 and -8 are also conserved andcontain a consensus site for phosphorylation by cAMP and cGMP-dependentprotein kinases.nd a target site for binding by PDZ domain proteins .

InterPro domains unassigned to SynO:
Several vertebrate small integral membrane glycoproteins are evolutionary related .ncluding eye lens specific membrane protein 20 (MP20 or MP19); epithelial membrane protein-1 (EMP-1).hich is also known as tumor-associatedmembrane protein (TMP) or as squamous cell-specific protein Cl-20; epithelial membrane protein-2 (EMP-2).hich is also known as XMP; epithelial membrane protein-3 (EMP-3).lso known as YMP;and peripheral myelin protein 22 (PMP-22).hich is expressed in many tissues but mainly by Schwann cells as a component of myelin of the peripheral nervous system (PNS). PMP-22 probably plays a role both in myelinization and in cell proliferation. Mutations affecting PMP-22 are associated with hereditary motor and sensory neuropathies such as Charcot-Marie-Tooth disease type 1A (CMT-1A) in human or the trembler phenotype in mice. The proteins of this family are about 160 to 173 amino acid residues in size.nd contain four transmembrane segments. PMP-22.MP-1.2 and -3 are highly similar.hile MP20 is more distantly related. This family also includes the claudins.hich are components of tight junctions.
