WebG 단백질 연결 수용체 (G protein coupled receptor, GPCR )는 7-막관통 수용체 (7-Transmembrane receptor, 7TMR )라고도 불린다. 이름에서 알 수 있듯이 [그림 1]에서 살펴보면 이것의 구조는 세포막 혹은 세포 내의 기관의 세포막 에서 세포질 면과 세포 외면에 걸쳐있고 막을 7번 ... GPCRs become desensitized when exposed to their ligand for a long period of time. There are two recognized forms of desensitization: 1) homologous desensitization, in which the activated GPCR is downregulated; and 2) heterologous desensitization, wherein the activated GPCR causes downregulation of a different GPCR. The key reaction of this downregulation is the phosphorylation of the intracellular (or cytoplasmic) receptor domain by protein kinases. eagle entertainer bus lennon hendrix holly
