Summary
Predicted to enable SH3 domain binding activity and cytoskeletal regulatory protein binding activity. Predicted to be involved in regulation of modification of postsynaptic actin cytoskeleton. Predicted to act upstream of or within actin cytoskeleton organization. Located in dendritic spine. Part of FAR/SIN/STRIPAK complex. Is active in glutamatergic synapse and postsynaptic actin cytoskeleton. Is expressed in brain; dorsal grey horn; glans of male genital tubercle; intestine smooth muscle circular layer; and limb. Orthologous to human CTTNBP2 (cortactin binding protein 2). [provided by Alliance of Genome Resources, Nov 2024]

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.
