Summary
This gene encodes a member of the metallo-beta-lactamase family. The encoded protein is a 73kDa subunit of the cleavage and polyadenylation specificity factor and functions as an endonuclease that recognizes the pre-mRNA 3'-cleavage site AAUAAA prior to polyadenylation. It also cleaves after the pre-mRNA sequence ACCCA during histone 3'-end pre-mRNA processing. [provided by RefSeq, Oct 2012]

Tat tat 73 kDa subunit of the cleavage and polyadenylation specificity factor (CPSF-73) and its homologue RC-68 repress the HIV-1 LTR promoter. The LTR region between -275 to -110 within the 5' upstream region is necessary for the CPSF-73 interaction PubMed
tat HIV-1 Tat interacts with CPSF-73 and counteracts its repressive activity on the HIV-1 LTR promoter. The N-terminal 48 amino acid residues of Tat are sufficient to mediate the interaction with CPSF-73 PubMed
tat HIV-1 Tat specifically increases the expression of the cleavage and polyadenylation specificity factor 73-kDa subunit (CPSF3), and this upregulation is an important regulatory step for both viral and cellular gene expression 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.
