Muscleblind-like protein 2 (MBNL2)

Acts either as activator or repressor of splicing on particular pre-mRNA targets. Inhibits cardiac troponin-T (TNNT2) pre-mRNA exon inclusion but induces insulin receptor (IR) pre-mRNA exon inclusion in muscle.

Antagonizes the alternative splicing activity pattern of CELF proteins. RNA-binding protein which binds to 5'ACACCC-3' core sequence, termed zipcode, within the 3'UTR of ITGA3.
