CC -!- FUNCTION: Component of the spliceosomal U1 snRNP, which is essential
CC for recognition of the pre-mRNA 5' splice-site and the subsequent
CC assembly of the spliceosome. U1-C is directly involved in initial 5'
CC splice-site recognition for both constitutive and regulated alternative
CC splicing. The interaction with the 5' splice-site seems to precede
CC base-pairing between the pre-mRNA and the U1 snRNA. Stimulates
CC commitment or early (E) complex formation by stabilizing the base
CC pairing of the 5' end of the U1 snRNA and the 5' splice-site region.
CC {ECO:0000255|HAMAP-Rule:MF_03153}.
CC -!- SUBUNIT: U1 snRNP is composed of the 7 core Sm proteins B/B', D1, D2,
CC D3, E, F and G that assemble in a heptameric protein ring on the Sm
CC site of the small nuclear RNA to form the core snRNP, and at least 3 U1
CC snRNP-specific proteins U1-70K, U1-A and U1-C. U1-C interacts with U1
CC snRNA and the 5' splice-site region of the pre-mRNA.
CC {ECO:0000255|HAMAP-Rule:MF_03153}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|HAMAP-Rule:MF_03153}.
CC -!- SIMILARITY: Belongs to the U1 small nuclear ribonucleoprotein C family.
CC {ECO:0000255|HAMAP-Rule:MF_03153}.
