Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
GPCR Desensitization
GPCRs Regulate Adenylyl Cylase Activity
Co-activators and Co-repressors
TGF - β Signaling Pathway
Receptor Downregulation in MVBs
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...
