Gene
pie-1
Protein
Pharynx and intestine in excess protein 1
Organism
Caenorhabditis elegans
Length
335 amino acids
Function
Maternally provided PIE-1 is required for germline cell fate determination. Functions as a repressor of RNA polymerase II-dependent gene expression in the developing germline. Required for expression of nos-2 in P4 germline blastomere cells. Inhibits the histone deacetylase activity of hda-1. Represses transcriptional activation of cdk-9 and cit-1.1, which are members of the P-TEFb complex.
