Summary: Enables kinase binding activity. Involved in synaptic membrane adhesion. Acts upstream of or within homophilic cell adhesion via plasma membrane adhesion molecules and positive regulation of inhibitory postsynaptic potential. Located in dendrite; inhibitory synapse; and neuronal cell body. Is active in GABA-ergic synapse. Is expressed in hippocampus CA1 and thalamic nucleus. Orthologous to human IGSF9B (immunoglobulin superfamily member 9B). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Broad expression in cerebellum adult (RPKM 6.7), cortex adult (RPKM 5.5) and 19 other tissues See more

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.
