PLK4 - polo like kinase 4 Gene

Also Known as SAK; STK18; MCCRP2

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 10733

About PLK4

Cytogenetic location: 4q28.1 Genomic coordinates (GRCh38): 4:127,880,893-127,899,224 (from NCBI)

This gene has 11 transcripts (splice variants), 210 orthologues, 4 paralogues and is associated with 5 phenotypes. Biased expression in testis (RPKM 12.2), bone marrow (RPKM 8.2) and 12 other tissues.

Summary

This gene encodes a member of the polo family of serine/threonine protein kinases. The protein localizes to centrioles, complex microtubule-based structures found in centrosomes, and regulates centriole duplication during the cell cycle. Three alternatively spliced transcript variants that encode different protein isoforms have been found for this gene. [provided by RefSeq, Jun 2010]
