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. SNRPC/U1-C is directly involved in initial
CC 5' splice-site recognition for both constitutive and regulated
CC alternative splicing. The interaction with the 5' splice-site seems to
CC precede 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: Component of the U1 snRNP. The U1 snRNP is composed of the U1
CC snRNA and the 7 core Sm proteins SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE,
CC SNRPF and SNRPG 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 SNRNP70/U1-70K, SNRPA/U1-A and SNRPC/U1-C.
CC SNRPC/U1-C interacts with U1 snRNA and the 5' splice-site region of the
CC pre-mRNA (By similarity). Interacts (via N-terminus) with TIA1 (via C-
CC terminus); thereby promoting spliceosomal U1 snRNP recruitment to 5'
CC splice sites (By similarity). {ECO:0000250|UniProtKB:P09234,
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}.
