Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid metabolite that regulates diverse biologic processes. SGPP1 catalyzes the degradation of S1P via...
Proline-rich peptide sequences have been shown to play important roles in protein-protein interactions that occur in signal transduction pathways. Specific...
SH3BP2 has an N-terminal pleckstrin homology (PH) domain, an SH3-binding proline-rich region, and a C-terminal SH2 domain. The protein binds to the SH3...
SHBG is a glycoprotein that binds to sex hormones, specifically testosterone and estradiol. Other steroid hormones such as progesterone, cortisol, and other...
The SHC gene encodes a signaling and transforming protein containing Src homology 2 and 3 (SH2 and SH3) domains. The SHC gene encodes 2 widely expressed...
Sonic hedgehog (Shh) is a member of a small family of secreted proteins that are essential for development in both vertebrates and invertebrates. In mammals,...
Congenital sucrase-isomaltase deficiency is an example of a disease in which mutation results in transport-incompetent molecules. sucrase-isomaltase is not...
