Summary: Enables phosphatidylinositol binding activity; protein kinase binding activity; and signaling adaptor activity. Involved in several processes, including positive regulation of Rac protein signal transduction; positive regulation of protein tyrosine kinase activity; and positive regulation of skeletal muscle acetylcholine-gated channel clustering. Acts upstream of or within neuromuscular junction development; positive regulation of protein phosphorylation; and receptor clustering. Is active in neuromuscular junction and postsynaptic membrane. Is expressed in several structures, including central nervous system; heart; musculature; and testis. Used to study congenital myasthenic syndrome 10. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 10 and fetal akinesia deformation sequence syndrome 3. Orthologous to human DOK7 (docking protein 7).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
