SPDL1 Gene

spindle apparatus coiled-coil protein 1

This gene encodes a coiled-coil domain-containing protein that functions in mitotic spindle formation and chromosome segregation. The encoded protein plays a role in coordinating microtubule attachment by promoting recruitment of dynein proteins, and in mitotic checkpoint signaling. [provided by RefSeq, Jul 2016]

MZT2A Gene

mitotic spindle organizing protein 2A

Located in centrosome; cytosol; and nucleoplasm. [provided by Alliance of Genome Resources, Mar 2025]

MZT2B Gene

mitotic spindle organizing protein 2B

Located in cytosol; microtubule cytoskeleton; and nucleoplasm. Part of gamma-tubulin ring complex. [provided by Alliance of Genome Resources, Mar 2025]

SASS6 Gene

spindle assembly 6 homolog (C. elegans)

The protein encoded by this gene is a central component of centrioles and is necessary for their duplication and function. Centrioles adopt a cartwheel-shaped structure, with the encoded protein forming the hub and spokes inside a microtubule cylinder. Defects in this gene are a cause of autosomal recessive primary microcephaly. [provided by RefSeq, Oct 2016]

MISP Gene

mitotic spindle positioning

The protein encoded by this gene is an actin-bundling protein involved in determining cell morphology and mitotic progression. The encoded protein is required for the proper positioning of the mitotic spindle. Two transcript variants, one protein-coding and the other non-protein coding, have been found for this gene.

MZT1P2 Gene

mitotic spindle organizing protein 1 pseudogene 2

MZT1 Gene

mitotic spindle organizing protein 1

Involved in gamma-tubulin complex localization. Located in centrosome and spindle. Part of gamma-tubulin ring complex. [provided by Alliance of Genome Resources, Mar 2025]

ESPL1 Gene

extra spindle pole bodies homolog 1 (S. cerevisiae)

Stable cohesion between sister chromatids before anaphase and their timely separation during anaphase are critical for chromosome inheritance. In vertebrates, sister chromatid cohesion is released in 2 steps via distinct mechanisms. The first step involves phosphorylation of STAG1 (MIM 604358) or STAG2 (MIM 300826) in the cohesin complex. The second step involves cleavage of the cohesin subunit SCC1 (RAD21; MIM 606462) by ESPL1, or separase, which initiates the final separation of sister chromatids (Sun et al., 2009 [PubMed 19345191]).[supplied by OMIM, Nov 2010]
