Domain

Transcription elongation factor Spt5, NGN domain (IPR005100)

Short name: TF_Spt5_NGN-domain

Domain relationships

None.

Description

Spt5p and prokaryotic NusG are shown to contain a novel 'NGN' domain. The combined NGN and KOW motif regions of Spt5 form the binding domain with Spt4 [PMID: 12202748]. Spt5 complexes with Spt4 as a 1:1 heterodimer snf this Spt5-Spt4 complex regulates early transcription elongation by RNA polymerase II and has an imputed role in pre-mRNA processing via its physical association with mRNA capping enzymes. The Schizosaccharomyces pombe core Spt5-Spt4 complex is a heterodimer bearing a trypsin-resistant Spt4-binding domain within the Spt5 subunit [PMID: 19460865].
