Protein Information (annotations from UniProt)

Database IDHIV0001561
UniProt IDQ99661
Primary gene name(s)KIF2C
Synonym gene name(s)KNSL6
Protein nameKinesin-like protein KIF2C
Protein functionIn complex with KIF18B, constitutes the major microtubule plus-end depolymerizing activity in mitotic cells, PubMed:21820309. Regulates the turnover of microtubules at the kinetochore and functions in chromosome segregation during mitosis, PubMed:19060894. Plays a role in chromosome congression and is required for the lateral to end-on conversion of the chromosome-microtubule attachment, PubMed:23891108. {ECO:0000269|PubMed:19060894, ECO:0000269|PubMed:21820309, ECO:0000269|PubMed:23891108}.
Subcellular locationCytoplasm, cytoskeleton {ECO:0000269|PubMed:19632184, ECO:0000269|PubMed:21820309, ECO:0000269|PubMed:23891108}. Nucleus {ECO:0000250|UniProtKB:P70096}. Chromosome, centromere {ECO:0000269|PubMed:14960279, ECO:0000269|PubMed:17485487}. Chromosome, centromere, kinetochore {ECO:0000269|PubMed:14960279, ECO:0000269|PubMed:17485487, ECO:0000269|PubMed:23891108}. Note=Associates with the microtubule network at the growing distal tip, the plus-end of microtubules, probably through interaction with MTUS2/TIP150 and MAPRE1, By similarity. Association with microtubule plus ends is also mediated by interaction with KIF18B. Centromeric localization requires the presence of BUB1 and SGO2. {ECO:0000250|UniProtKB:P70096, ECO:0000269|PubMed:17485487, ECO:0000269|PubMed:21820309}.
