UniProtKB - A0A0N4Y3E1 (A0A0N4Y3E1_NIPBR)
Protein
U1 small nuclear ribonucleoprotein C
Gene
NBR_LOCUS10315
Organism
Nippostrongylus brasiliensis (Rat hookworm)
Status
Functioni
Component of the U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. U1-C is directly involved in initial 5' splice-site recognition for both constitutive and regulated alternative splicing. The interaction with the 5' splice-site seems to precede base-pairing between the pre-mRNA and the U1 snRNA.UniRule annotation
Component of the spliceosomal U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. U1-C is directly involved in initial 5' splice-site recognition for both constitutive and regulated alternative splicing. The interaction with the 5' splice-site seems to precede base-pairing between the pre-mRNA and the U1 snRNA. Stimulates commitment or early (E) complex formation by stabilizing the base pairing of the 5' end of the U1 snRNA and the 5' splice-site region.UniRule annotation

Subunit structurei
U1 snRNP is composed of the 7 core Sm proteins B/B', D1, D2, D3, E, F and G that assemble in a heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP, and at least 3 U1 snRNP-specific proteins U1-70K, U1-A and U1-C. U1-C interacts with U1 snRNA and the 5' splice-site region of the pre-mRNA.
