About STK4

Cytogenetic location: 20q13.12 Genomic coordinates (GRCh38): 20:44,966,512-45,080,021 (from NCBI)

This gene has 17 transcripts (splice variants), 130 orthologues, 35 paralogues and is associated with 2 phenotypes. Broad expression in lymph node (RPKM 17.1), appendix (RPKM 14.6) and 24 other tissues.

Summary

The protein encoded by this gene is a cytoplasmic kinase that is structurally similar to the yeast Ste20p kinase, which acts upstream of the stress-induced mitogen-activated protein kinase cascade. The encoded protein can phosphorylate myelin basic protein and undergoes autophosphorylation. A caspase-cleaved fragment of the encoded protein has been shown to be capable of phosphorylating histone H2B. The particular phosphorylation catalyzed by this protein has been correlated with Apoptosis, and it's possible that this protein induces the chromatin condensation observed in this process.
