UniProt functional annotation for Q64487

UniProt code: Q64487.

Organism: Mus musculus (Mouse).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus.
 
Function: Can bidirectionally induce pre- and post-synaptic differentiation of neurons by mediating interaction with IL1RAP and IL1RAPL1 trans-synaptically (PubMed:25908590). Involved in pre-synaptic differentiation through interaction with SLITRK2 (PubMed:25989451). {ECO:0000269|PubMed:25908590, ECO:0000269|PubMed:25989451}.
 
Catalytic activity: Reaction=H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] + phosphate; Xref=Rhea:RHEA:10684, Rhea:RHEA-COMP:10136, Rhea:RHEA- COMP:10137, ChEBI:CHEBI:15377, ChEBI:CHEBI:43474, ChEBI:CHEBI:46858, ChEBI:CHEBI:82620; EC=3.1.3.48; Evidence={ECO:0000255|PROSITE- ProRule:PRU10044};
Subunit: Interacts with PPFIA1, PPFIA2 and PPFIA3 (By similarity). Interacts (via extracellular domain) with SLITRK4 (via LRR 1 and 2 repeats) (PubMed:25989451). Interacts with SLITRK2; induces presynaptic differentiation (PubMed:25989451). Interacts (via the second immunoglobilin domain) with IL1RAPL1 (via the first immunoglobilin domain); induces pre- and postsynaptic differentiation of neurons and synapse formation. Isoform G, isoform H, isoform I, isoform J, and isoform K do not interact with IL1RAPL1 (PubMed:25908590, PubMed:21940441). Interacts (via the third immunoglobilin domain) with IL1RAP (via the first immunoglobilin domain); induces pre- and postsynaptic differentiation of neurons (PubMed:25908590). {ECO:0000250|UniProtKB:P23468, ECO:0000269|PubMed:21940441, ECO:0000269|PubMed:25908590, ECO:0000269|PubMed:25989451}.
Subcellular location: Membrane; Single-pass type I membrane protein.
Tissue specificity: Brain, kidney, heart, and some B-cell lines.
Ptm: A cleavage occurs, separating the extracellular domain from the transmembrane segment. This process called 'ectodomain shedding' is thought to be involved in receptor desensitization, signal transduction and/or membrane localization (By similarity). {ECO:0000250}.
Similarity: Belongs to the protein-tyrosine phosphatase family. Receptor class 2A subfamily. {ECO:0000305}.
Sequence caution: Sequence=BAA03004.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
