Myocardial zonula adherens protein (Myzap)

Plays a role in cellular signaling via Rho-related GTP- binding proteins and activation of transcription factor SRF. Targets TJP1 to cell junctions (By similarity).

In cortical neurons, may play a role in glutaminergic signal transduction through interaction with the NMDA receptor subunit GRIN1 (By similarity). .
