Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Plus end-directed microtubule-dependent motor required for normal brain development. May regulate microtubule dynamics during axonal growth. Required for normal progression through mitosis. Required for normal congress of chromosomes at the metaphase plate. Required for normal spindle dynamics during mitosis. Promotes spindle turnover. Implicated in formation of bipolar mitotic spindles. Has microtubule depolymerization activity.SUBUNIT Interacts with AURKA and PLK1 (PubMed:19351716). Interacts with PSRC1 (PubMed:18411309). Interacts with MCRS1; the interaction enhances recruitment of KIF2A to the minus ends of spindle microtubules which promotes chromosome alignment (PubMed:30785839).INTERACTION Localized to the spindle microtubules and spindle poles from prophase to metaphase. Efficient targeting to spindle microtubules and spindle poles requires the kinase activity of PLK1. Recruited to mitotic spindles by interaction with PSRC1.ALTERNATIVE PRODUCTS The disease is caused by variants affecting the gene represented in this entry.MISCELLANEOUS HeLa cells lacking KIF2A show asymmetric or monopolar mitotic spindles. Osteosarcoma cells (U2OS) lacking KIF2A or KIF2B show disorganised or monopolar mitotic spindles.SIMILARITY Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. MCAK/KIF2 subfamily.SEQUENCE CAUTION Truncated N-terminus.
