EPDR1 (Epidermal growth factor receptor pathway substrate 15-related protein 1): Similar to MMP15's role in extracellular matrix (ECM) dynamics, EPDR1 is implicated in cellular signaling pathways that regulate various physiological processes, including cell proliferation, survival, and differentiation. As a member of the epidermal growth factor receptor (EGFR) pathway substrate family, EPDR1 interacts with key signaling molecules involved in growth factor signaling cascades, modulating downstream signaling events. This protein plays a critical role in mediating cellular responses to extracellular stimuli, such as growth factors and cytokines, thereby influencing cell fate decisions and tissue homeostasis. Dysregulation of EPDR1 expression or activity has...
