Bm3183 | U1 small nuclear ribonucleoprotein C; 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; Belongs to the U1 small nuclear ribonucleoprotein C family. (144 aa) | ||||
A0A5S6PJT4 | U1 small nuclear ribonucleoprotein C. (128 aa) |
