Study in mutant mice and human cerebral organoids showed that WDR62 deletion resulted in a reduction in the size of mouse brains and organoids due to the disruption of neural progenitor cells. WDR62 interacts with and promotes CEP170 localization to the basal body of primary cilium, where CEP170 recruits KIF2A to disassemble cilium.

Heterodimeric KIF3AC and KIF3AB, two members of the mammalian kinesin-2 family, generate force for microtubule plus end-directed cargo transport. This study reveals the impact of heterodimerization of the motor polypeptides for microtubule association to start the processive run and the fundamental differences in the motile properties of KIF3C compared with KIF3A and KIF3B.

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.

NM_001145779.1 → NP_001139251.1 kinesin-like protein KIF2A isoform 2

See identical proteins and their annotated locations for NP_001139251.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an alternate exon in the 5' coding region and in the 3' coding region, compared to variant 1. An upstream start codon with a strong Kozak signal is used by this variant. The predicted protein (isoform 2) has a longer and distinct N-terminus and a shorter C-terminus when it is compared to isoform 1.
