Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: FLA8; RP89; HH0048; KLP-11; OTSC12
Summary: The protein encoded by this gene acts as a heterodimer with kinesin family member 3A to aid in chromosome movement during mitosis and meiosis. The encoded protein is a plus end-directed microtubule motor and can interact with the SMC3 subunit of the cohesin complex. In addition, the encoded protein may be involved in the intracellular movement of membranous organelles. This protein and kinesin family member 3A form the kinesin II subfamily of the kinesin superfamily. [provided by RefSeq, Jul 2008]

miR-127-3p was downregulated in oral squamous cell carcinoma (OSCC) tissues and was associated with malignant clinicopathological features and poor prognosis. KIF3B was confirmed to be a direct target of miR-127-3p. Upregulation of KIF3B observed in OSCC promoted tumorigenesis. miR-127-3p targeted KIF3B to inhibit the development of OSCC by suppressing cell proliferation, migration and invasion.

The rate of transport is set by an equilibrium between a faster state, where only kinesin family member 17 protein (KIF17) motors move the train, and a slower state, where at least one kinesin family member 3A/B protein (KIF3AB) motor on the train remains active in transport.

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.
