Predicted to enable ATP binding activity; MAP kinase kinase kinase kinase activity; and SH3 domain binding activity. Predicted to be involved in several processes, including protein phosphorylation; response to UV; and response to tumor necrosis factor. Predicted to act upstream of or within phosphorylation. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human MAP4K3 (mitogen-activated protein kinase kinase kinase kinase 3). [provided by Alliance of Genome Resources, Apr 2022]
