FRG1 (Q14331) - Overview - Molecular Target Synopsis


FRG1, Protein FRG1
UniProt Q14331

Also Known as FRG1_HUMAN, FRG1

Binds to mRNA in a sequence-independent manner. May play a role in regulation of pre-mRNA splicing or in the assembly of rRNA into ribosomal subunits. May be involved in mRNA transport. May be involved in epigenetic regulation of muscle differentiation through regulation of activity of the histone-lysine N-methyltransferase KMT5B. Homodimer and homotetramer in solution. Identified in the spliceosome C complex. Interacts with KMT5B (via C-terminus). Interacts (via N-terminus) with KPNA2 and NXF1/TAP. Interacts with F-actin with a stoichiometry of 2:1.
