Predicted to enable ubiquitin-protein transferase activity. Predicted to be involved in protein autoubiquitination; regulation of megakaryocyte differentiation; and ubiquitin-dependent protein catabolic process. Predicted to be located in cytoplasm and nucleus. Predicted to be part of CCR4-NOT complex. Is expressed in several structures, including central nervous system; genitourinary system; and neural retina. Orthologous to human CNOT4 (CCR4-NOT transcription complex subunit 4).
