Predicted to enable cysteine-type endopeptidase inhibitor activity involved in apoptotic process; protein kinase binding activity; and ribosomal protein S6 kinase activity. Predicted to be involved in several processes, including negative regulation of cysteine-type endopeptidase activity involved in apoptotic process; peptidyl-serine phosphorylation; and response to lipopolysaccharide. Predicted to be located in cytosol and nucleolus. Predicted to be active in cytoplasm and nucleoplasm. Human ortholog(s) of this gene implicated in Coffin-Lowry syndrome; intellectual disability; and non-syndromic X-linked intellectual disability 19. Orthologous to human RPS6KA3 (ribosomal protein S6 kinase A3). [provided by Alliance of Genome Resources, Apr 2022]
