Summary: Enables G-protein beta/gamma-subunit complex binding activity; heterotrimeric G-protein binding activity; and microtubule binding activity. Involved in spermatogenesis. Located in several cellular components, including 9+2 motile cilium; microtubule organizing center; and photoreceptor connecting cilium. Is expressed in 4th ventricle lateral recess; choroid plexus; and lateral ventricle choroid plexus. Orthologous to human CETN2 (centrin 2). [provided by Alliance of Genome Resources, Nov 2024]

What's a GeneRIF?

Removal of CETN2 and CETN3 activity from the lumen of the connecting cilium (CC) destabilized the photoreceptor axoneme and reduced the CC length as early as postnatal day 22 (P22).

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.
