Solution structure of the RRM_1 domain of HIV TAT specific factor 1 variant

Structural highlights

2dit is a 1 chain structure with sequence from Homo sapiens. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	Solution NMR
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN

Function

HTSF1_HUMAN Functions as a general transcription factor playing a role in the process of transcriptional elongation. May mediate the reciprocal stimulatory effect of splicing on transcriptional elongation. In case of infection by HIV-1, it is up-regulated by the HIV-1 proteins NEF and gp120, acts as a cofactor required for the Tat-enhanced transcription of the virus.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8]
