C5a receptor

The C5a receptor also known as complement component 5a receptor 1 (C5AR1) or CD88 (Cluster of Differentiation 88) is a G protein-coupled receptor for C5a. It functions as a complement receptor.[5] C5a receptor 1 modulates inflammatory responses, obesity, development and cancers.[6][7][8] From a signaling transduction perspective, C5a receptor 1 activation is implicated in β-arrestin2 recruitment via Rab5a,[9] coupling of Gαi proteins,[10] ERK1/2 phosphorylation, [11] calcium mobilization and Rho activation[12] leading to downstream functions, such as secretion of cytokines, chemotaxis, and phagocytosis.
