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.

C5a receptor structure and its residues possessing role in ligand binding or signaling.
