Summary: Enables RNA polymerase II complex binding activity; chromatin binding activity; and mRNA binding activity. Involved in regulation of DNA-templated transcription; sex-chromosome dosage compensation; and transcription elongation by RNA polymerase II. Located in polytene chromosome interband and polytene chromosome puff. Part of DSIF complex. Is expressed in adult head and organism. Orthologous to human SUPT5H (SPT5 homolog, DSIF elongation factor subunit). [provided by Alliance of Genome Resources, Dec 2024]

Spt5 interacts both physically and genetically with the Polycomb Group (PcG) protein Pleiohomeotic (Pho)
Title: Pleiohomeotic interacts with the core transcription elongation factor Spt5 to regulate gene expression in Drosophila.
We show that SPT5 interacts directly with MSL1 in vitro and is required downstream of MSL complex recruitment, providing the first mechanistic data corroborating the elongation model of dosage compensation.
