Functioni

Promotes dimerization of NF-kappa-B subunits and regulates NF-kappa-B transcription factor activity (By similarity). Plays a role in the regulation of the growth of actin filaments. Inhibits the activity of the F-actin-capping protein complex formed by the CAPZA1 and CAPZB heterodimer. Promotes growth of cardiomyocytes, but not cardiomyocyte proliferation. Promotes cardiac muscle hypertrophy.By similarity3 Publications

Miscellaneous

This protein is produced by a bicistronic gene which also produces the MPD6 protein from a non-overlapping reading frame. MPD6 belongs to a group of cryptic antigens without conventional genomic structure. It is encoded by a cryptic open reading frame located in the 3'-untranslated region of MTPN.
