Function

This gene is a member of the serine/threonine protein kinase family and encodes a phosphoprotein with a PX (phox homology) domain. The protein phosphorylates several target proteins and has a role in neutral amino acid transport and activation of potassium and chloride channels. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.[7]

In melanocytic cells SGK3 gene expression may be regulated by MITF.[8]

Interactions

SGK3 has been shown to interact with GSK3B.[9]
