Description
General description
Heterogeneous nuclear ribonucleoprotein Q commoly refered to as hnRNP Q can be found as three different isoforms derived from alternative splicing of a single gene. This RNA binding protein is implicated in control of mRNA precursor splicing for the survival of motor neurons (SMN) protein, a gene. Loss-of-function mutations of SMN are linked to spinal muscular atrophy (SMA) a common neurodegenerative disease. It has been shown that hnRNP Q proteins interact with SMN, and this is interacton is required for efficient pre-mRNA splicing in vitro. Current data suggests that hnRNP Q is a splicing modulator of SMN.
The calculated molecular weight is 70 kDa Clone 18E4 can recognizes four bands on the Western Blot of total HeLa cell lysate corresponding to molecular masses of ~80, ~70, ~60 and ~55 kDa hnRNP Q has three isoforms of ~70– 55 kDa The ~80 kDa reactive band was identified as hnRNP R, which migrates at ~80 kDa on SDS–PAGE.
