Rabbit Anti-hnRNP C1/C2/FITC Conjugated antibody
background:
Binds pre-mRNA and nucleates the assembly of 40S hnRNP particles. Single HNRNPC tetramers bind 230-48 nucleotides. Trimers of HNRNPC tetramers bind 700 nucleotides. May play a role in the early steps of spliceosome assembly and pre-mRNA splicing. 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.
Function:
UniProtKB/Swiss-Prot: P07910.4
Subunit:
Tetramer composed of 3 copies of isoform C1 and 1 copy of isoform C2. Assembly of 3 tetramers with bound pre-mRNA gives rise to a 19S complex that interacts with HNRNPA2B1 tetramers. Component of the 40S hnRNP particle. Identified in the spliceosome C complex. Interacts with IGF2BP1.
Subcellular Location:
Nucleus. Component of ribonucleosomes.
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.
Similarity:
Belongs to the RRM HNRPC family. RALY subfamily.
Contains 1 RRM (RNA recognition motif) domain.
