Smad4 | Mothers against decapentaplegic homolog 4; Common SMAD (co-SMAD) is the coactivator and mediator of signal transduction by TGF-beta (transforming growth factor). Component of the heterotrimeric SMAD2/SMAD3-SMAD4 complex that forms in the nucleus and is required for the TGF-mediated signaling. Promotes binding of the SMAD2/SMAD4/FAST-1 complex to DNA and provides an activation function required for SMAD1 or SMAD2 to stimulate transcription. Component of the multimeric SMAD3/SMAD4/JUN/FOS complex which forms at the AP1 promoter site; required for synergistic transcriptional activity in r [...] (551 aa) | ||||
Ly6g6e | Lymphocyte antigen 6G6e; Believed to act as a modulator of nicotinic acetylcholine receptors (nAChRs) activity. In vitro potentiates alpha-3:beta-4- containing nAChRs maximum response by increasing peak current and slowing down receptor desensitization; the activity is dependent on its cell surface localization.
