Also known as: RBP4; RPB4; RPB16; HSRBP4; HSRPB4
Summary: This gene encodes the fourth largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. In yeast, this polymerase subunit is associated with the polymerase under suboptimal growth conditions and may have a stress protective role. A sequence for a ribosomal pseudogene is contained within the 3' untranslated region of the transcript from this gene. [provided by RefSeq, Jul 2008]

Envelope surface glycoprotein gp120	env	The transcription factors and kinases c-Jun, JNK, MEK, p38 MAPK, STAT-3, JAK-1, TFII D, TFII F, eIF-4E, and RNA polymerase II are induced by HIV-1 gp120	PubMed
Tat	tat	The interaction of Tip110 with HIV-1 Tat leads to a higher efficiency of elongation for RNAPII complexes formed on the LTR promoter	PubMed
	tat	Expression of both Tip110 and Tat enhances phosphorylation of RNAPII at both serine 2 and serine 5, which account for Tip110 function in transcription activation	PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
