Recombinant Human Protein SCAF8 (SCAF8), Truncated

Uniprot Id

Q9UPN6

Target Species

Human

Target Name

SCAF8

Target Full Name

SR-related and CTD-associated factor 8

Target Function

Anti-terminator protein required to prevent early mRNA termination during transcription. Together with SCAF4, acts by suppressing the use of early, alternative poly(A) sites, thereby preventing the accumulation of non-functional truncated proteins. Mechanistically, associates with the phosphorylated C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit (POLR2A), and subsequently binds nascent RNA upstream of early polyadenylation sites to prevent premature mRNA transcript cleavage and polyadenylation. Independently of SCAF4, also acts as a positive regulator of transcript elongation.

Target Subcellular Location

Nucleus. Nucleus matrix.

Target Synonyms

SCAF8; CCAP7; KIAA1116; RBM16; SR-related and CTD-associated factor 8; CDC5L complex-associated protein 7; RNA-binding motif protein 16

Target Background

Enables RNA binding activity and RNA polymerase II C-terminal domain phosphoserine binding activity. Involved in negative regulation of termination of RNA polymerase II transcription, poly(A)-coupled and positive regulation of DNA-templated transcription, elongation. Located in nucleoplasm.
