Predicted to enable armadillo repeat domain binding activity; molecular adaptor activity; and nuclear receptor binding activity. Predicted to contribute to poly(A)-specific ribonuclease activity. Involved in regulation of stem cell population maintenance and trophectodermal cell differentiation. Located in P-body. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in holoprosencephaly. Orthologous to human CNOT1 (CCR4-NOT transcription complex subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
