Developmental stage

Isoform 1 expressed at low level in 13 dpc embryonic hippocampus, higher level by stage 15 persisting into juvenile and adult stages. Isoform 2 expressed in 13 dpc and 15 dpc embryonic hippocampus declining to very low levels in juvenile and adult neurons. High level of isoform 1 and very low level of isoform 2 in stage 2 and 5 hippocampal neurons in culture.

Function

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 (By similarity).

Sequence similarities

Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. MCAK/KIF2 subfamily.

Tissue specificity

Highest level in lung. High level in ovary, moderate levels in heart, kidney, placenta, skeletal muscle and spleen (at protein level). Pancreas and spleen express a shorter isoform (at protein level). Expressed in the flagellum of elongated spermatids and sperm in the testis lumen (at protein level) (PubMed:24339785). Isoform 1 expressed in neuronal cells. Isoform 2 expressed in astrocytes and fibroblasts.

  • 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 (By similarity). Associated with lysosomes in NIH3T3 cells.
