Small Nuclear Ribonucleoprotein U5 Subunit 200 (SNRNP200)

Target
SNRNP200
Molecular classification
Helicase, RNA helicase, Ribonucleoprotein
01

Overview

SNRNP200 encodes a large RNA helicase that is a core component of the spliceosome complex, essential for pre-mRNA splicing. It catalyzes ATP-dependent unwinding of the U4/U6 RNA duplexes, a crucial step in assembling an active spliceosome. Mutations in SNRNP200 are linked to Retinitis Pigmentosa type 33 (RP33), an autosomal dominant retinal degenerative disease.
