Homo sapiens

Also known as SPT4; SPT4H; SUPT4H; Supt4a

Gene ID: 6827 | Gene type: protein coding

About SUPT4H1

Cytogenetic location: 17q22 Genomic coordinates (GRCh38): 17:58,345,178-58,352,201 (from NCBI)

This gene has 7 transcripts (splice variants) and 214 orthologues. Ubiquitous expression in bone marrow (RPKM 34.4), brain (RPKM 26.3) and 25 other tissues.

Summary

This gene encodes the small subunit of DRB (5,6-dichloro-1-beta-d-ribofuranosylbenzimidazole) sensitivity-inducing factor (DSIF) complex, which regulates mRNA processing and transcription elongation by RNA polymerase II. The encoded protein is localized to the nucleus and interacts with the large subunit (SUPT5H) to form the DSIF complex. Related pseudogenes have been identified on chromosomes 2 and 12. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 2012]
