Domain Architecture (Details)
InterPro domains unassigned to SynO:
This domain is found in diverse proteins homologous to inositol monophosphatase . These proteins are Mg2+-dependent/Li+-sensitive phosphatases. That catalyse a variety of reactions.
  IPR000300:Inositol polyphosphate related phosphatase
Synaptic vesicles are recycled with remarkable speed and precision in nerve terminals. A major recycling pathway involves clathrin-mediated endocytosis at endocytic zones located around sites of release. Different accessory proteins linked to this pathway have been shown to alter the shape and composition of lipid membranes.o modify membrane-coat protein interactions.nd to influence actin polymerization. These include the GTPase dynamin.he lysophosphatidic acid acyl transferase endophilin.nd the phosphoinositide phosphatase synaptojanin . The recessive suppressor of secretory defect in yeast Golgi and yeastactin function belongs to this family. This protein may be involved in the coordination of the activities of the secretory pathway and the actin cytoskeleton.Human synaptojanin which may be localised on coated endocytic intermediates in nerve terminals also belongs to this family.
  IPR002013:Synaptojanin, N-terminal
This domain is found in a large number of proteins including magnesium dependent endonucleases and phosphatases involved in intracellular signalling . Proteins this domain is found in include: AP endonuclease proteins ().Nase I proteins ().ynaptojanin an inositol-1..-trisphosphate phosphatase () and Sphingomyelinase ().
This entry represents nucleotide-binding domains with an alpha-beta plait structure.hich consists of either a ferredoxin-like (beta-alpha-beta)2 fold.uch as that found in RNA-binding domains of various ribonucleoproteins or in viral DNA-binding domains . or a beta-(alpha)-beta-alpha-beta(2) fold.uch as that found in the ribosomal protein L23 .
