Summary: Enables chromatin binding activity. Acts upstream of or within several processes, including keratinocyte development; negative regulation of keratinocyte proliferation; and non-motile cilium assembly. Located in centrosome; cilium; and nucleus. Part of intraciliary transport particle B. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and respiratory system. Used to study visceral heterotaxy. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome 22; Joubert syndrome; and spermatogenic failure 58. Orthologous to human IFT74 (intraflagellar transport 74).

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.
