General description

Muscle blind-like 1 (MBNL1) is a homolog of human muscle blind like proteins. Proteins of the MBNL (muscleblind-like) family are mainly expressed in skeletal muscle neuronal tissues, thymus, liver and kidney.

Immunogen

recombinant muscleblind-like1 (MBNL1) fusion protein.

Application

Monoclonal Anti-MBNL1 antibody produced in mouse has been used in: immunoblotting, immunohistochemistry and immunocytochemistry

Biochem/physiol Actions

Proteins of the MBNL (muscleblind-like) family enhance inclusion or exclusion of specific exons on different pre-mRNAs by inhibiting the activity of CUG-BP and ETR-3-like factors (CELF proteins) bound to distinct intronic sites. MBNL1 may be implicated in the stimulation of muscle differentiation. Mice knockouts for the MBNL1 gene develop muscle, eye, and RNA splicing abnormalities that are characteristic of the neuromuscular disease myotonic dystrophy (DM) disease.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
