SPT4/YGR063C Summary Help

Standard Name SPT4 1, 2
Systematic Name YGR063C
Feature Type ORF, Verified
Description Component of the universally conserved Spt4/5 complex (DSIF complex); the complex has multiple roles in concert with RNA polymerases I and II, including regulation of transcription elongation, RNA processing, quality control, and transcription-coupled DNA repair; Spt4p also localizes to kinetochores and heterochromatin and affects chromosome dynamics and silencing; required for transcription through lengthy trinucleotide repeats in ORFs or non-protein coding regions (3, 4, 5, 6, 7, 8, 9, 10, 11)
