Domain relationships


This entry represents the RNA recognition motif (RRM) of Nab3p (also known as Hmd1p), an acidic nuclear polyadenylated RNA-binding protein that is essential for cell viability. Nab3p is predominantly localized within the nucleoplasm and essential for growth in budding yeast [PMID: 7962083]. It plays an important role in the maintenance of CLN3 mRNA levels [PMID: 7476874]. It is part of the Nrd1 complex (Nrd1p-Nab3p-Sen1p) that directs the termination and processing of short RNA polymerase II transcripts and regulates cellular response to nutrient availability [PMID: 22431520].

Nab3p contains an N-terminal aspartic/glutamic acid-rich region, a central RNA recognition motif (RRM), and a C-terminal region rich in glutamine and proline residues [PMID: 20805243].
