Gene ID: 6788 | Gene type: protein coding

About STK3

Cytogenetic location: 8q22.2 Genomic coordinates (GRCh38): 8:98,343,975-98,942,610 (from NCBI)

This gene has 20 transcripts (splice variants), 277 orthologues and 35 paralogues. Ubiquitous expression in endometrium (RPKM 3.0), placenta (RPKM 2.4) and 25 other tissues.

Summary

This gene encodes a serine/threonine protein kinase activated by proapoptotic molecules indicating the encoded protein functions as a growth suppressor. Cleavage of the protein product by Caspase removes the inhibitory C-terminal portion. The N-terminal portion is transported to the nucleus where it homodimerizes to form the active kinase which promotes the condensation of chromatin during Apoptosis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]
