The FcRI complex forms a high-affinity cell-surface receptor for the Fc region of antigen-specific immunoglobulin E (IgE) molecules. FcRI is multimeric and is a member of a family of related antigen/Fc receptors which have conserved structural features and similar roles in initiating intracellular signalling cascades.
There are several types of steroid receptors. Type I receptors are present in the cytoplasm bound to other proteins. Once the hormone binds to it, it releases a transcription factor that crosses into the nucleus and attaches to a promoter region, initiating transcription of a particular gene (or genes).lso, i Know that peptide/protein and amino acid derivative hormones and lipophobic and cannot pas through the membrane. So it the hormone needs to bind to the receptor on the surface of the membrane, causing a cascade of events like activating the G protein, cAMP and some crap like that.
