HNRNPAB
Function
Binds single-stranded RNA. Has a high affinity for G-rich and U-rich regions of hnRNA. Also binds to APOB mRNA transcripts around the RNA editing site.
Post-translational modifications
Dimethylation at Arg-322 is probably asymmetric.
Tissue Specificity
Ubiquitous.
Cellular localization
- Nucleus
- Cytoplasm
- Localized in cytoplasmic mRNP granules containing untranslated mRNAs.
