Interacts with the dystrophin protein DMD and related proteins DTNA and UTRN, and with the neuroregulin receptor ERBB4.

Interacts with PTPRN when phosphorylated, protecting PTPRN from protein cleavage by CAPN1. Dephosphorylation upon insulin stimulation disrupts the interaction with PTPRN and results in the cleavage of PTPRN.

Interacts with DTNB (By similarity).

The sequence of this isoform differs from the canonical sequence as follows:

     268-540: Missing.

Note: Lacks domains required for interaction with dystrophin related proteins. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.Curated
