Background
This gene encodes a protein associated with the mitotic spindle apparatus. The encoded protein may be involved in the functional and dynamic regulation of mitotic spindles. [provided by RefSeq, Jul 2008],
Function
function:Necessary for normal spindle formation during mitosis.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,subcellular location:In a punctate pattern in interphase cells. During mitosis, detected at spindle poles during prophase, throughout the spindle in metaphase and anaphase, and at midzone microtubules in anaphase and telophase. Detected on kinetochores of chromosomes that have congressed.,subunit:Homodimer, with a globular head domain and a long stalk. Homo-oligomer; the globular head domains associate, resulting in aster-like structures. Binds to microtubules in the mitotic spindle.,tissue specificity:Highly expressed in testis. Detected at low levels in placenta, liver, pancreas, thymus and colon.,

During mitosis, detected at spindle poles during prophase, throughout the spindle in metaphase and anaphase, and at midzone microtubules in anaphase and telophase (PubMed:27462074). Efficient targeting to the mitotic spindle may depend upon phosphorylation by GSK3B. Detected on kinetochores of chromosomes that have congress
