Biological function summary
HnRNP C1/C2 participates in the assembly of large ribonucleoprotein complexes that are essential for mRNA metabolism. It acts as a core component of the spliceosome machinery where it influences the alternative splicing of pre-mRNA. Apart from its structural role hnRNP C1/C2 may contribute to the proper assembly and functioning of splicing factors and other proteins such as 4f4 within the nucleus suggesting its important role in gene expression regulation.
Pathways
HnRNP C1/C2 is involved in the RNA processing pathway directly impacting mRNA export and stability. By interacting with other proteins such as serine/arginine-rich splicing factors it modulates the splicing accuracy and efficiency of various transcripts. This participation in the spliceosome pathway emphasizes its importance in ensuring efficient gene expression and processing. hnRNP C1/C2 might also interact with various transcription machinery components linking RNA processing to transcriptional regulation.

General info
Function
Binds pre-mRNA and nucleates the assembly of 40S hnRNP particles (PubMed : 8264621). Interacts with poly-U tracts in the 3'-UTR or 5'-UTR of mRNA and modulates the stability and the level of translation of bound mRNA molecules (PubMed : 12509468, PubMed : 16010978, PubMed : 7567451, PubMed : 8264621). Single HNRNPC tetramers bind 230-240 nucleotides. Trimers of HNRNPC tetramers bind 700 nucleotides (PubMed : 8264621). May play a role in the early steps of spliceosome assembly and pre-mRNA splicing. N6-methyladenosine (m6A) has been shown to alter the local structure in mRNAs and long non-coding RNAs (lncRNAs) via a mechanism named 'm(6)A-switch', facilitating binding of HNRNPC, leading to regulation of mRNA splicing (PubMed : 25719671).
Sequence similarities
Belongs to the RRM HNRPC family. RALY subfamily.
Post-translational modifications
Phosphorylated on Ser-260 and Ser-299 in resting cells. Phosphorylated on Ser-253 and on 1 serine residue in the poly-Ser stretch at position 238 in response to hydrogen peroxide.. Sumoylated. Sumoylation reduces affinity for mRNA.. Ubiquitinated and degraded after nucleo-cytoplasmic transport by YWHAE.
