CNKSR3 Protein, Human (sf9, GST)

CNKSR3 protein regulates transepithelial sodium transport by controlling aldosterone-induced ENaC-mediated sodium transport. As a scaffolding protein, CNKSR3 coordinates ENaC regulatory complex (ERC) assembly and directly interacts with ENaC subunits SCNN1A and SCNN1B. CNKSR3 Protein, Human (sf9, GST) is the recombinant human-derived CNKSR3 protein, expressed by Sf9 insect cells , with N-GST labeled tag. The total length of CNKSR3 Protein, Human (sf9, GST) is 352 a.a., with molecular weight of 53-65 kDa.

The CNKSR3 Protein plays a pivotal role in the modulation of transepithelial sodium transport by regulating aldosterone-induced and epithelial sodium channel (ENaC)-mediated sodium transport through precise control of ENaC cell surface expression. Functioning as a scaffold protein, CNKSR3 orchestrates the assembly of an ENaC-regulatory complex (ERC). Its direct interaction with the C-terminal tails of ENaC subunits, SCNN1A α and SCNN1B β, underscores its involvement in coordinating the formation of the regulatory complex. Moreover, CNKSR3 interacts with key players in the ENaC regulatory network, including NEDD4L, RAF1, and SGK1, highlighting its role as a central mediator in the intricate regulation of sodium transport across epithelial cells. The multifaceted interactions of CNKSR3 emphasize its significance in the fine-tuning of sodium homeostasis and underline its position as a crucial player in the complex machinery governing ion transport processes.
