In mammals, complement C5a receptor (C5aR) is a member of the G protein-coupled receptor family (GPCRs) (Boulay et al. 1991; Gerard NP and Gerard C 1991). C5aR is activated upon binding of complement fragment C5a. C5aR transduces signals through multiple pathways, leading to the inhibition of adenylyl cyclase, activation of MAP kinase, phosphoinositol accumulation and calcium mobilization [Sayah S et al 2003; Ricklin D et al 2010; Wrann CD et al 2007].

Chicken C5aR mRNA was detected in liver and in various eye tissues (Haynes T et al. 2013). The binding of chicken C5a to C5aR has not been verified experimentally but is inferred from properties of the orthologous human proteins.
