Evolution of the CD163 family and its relationship to the bovine gamma delta T cell co-receptor WC1.

ABSTRACT:

Background

The scavenger receptor cysteine rich (SRCR) domain is an ancient and conserved protein domain. CD163 and WC1 molecules are classed together as group B SRCR superfamily members, along with Spalpha, CD5 and CD6, all of which are expressed by immune system cells. There are three known types of CD163 molecules in mammals, CD163A (M130, coded for by CD163), CD163b (M160, coded for by CD163L1) and CD163c-alpha (CD163L1 or SCART), while their nearest relative, WC1, is encoded by a multigene family so far identified in the artiodactyl species of cattle, sheep, and pigs.

Results

We annotated the bovine genome and identified genes coding for bovine CD163A and CD163c-alpha but found no evidence for CD163b. Bovine CD163A is widely expressed in immune cells, whereas CD163c-alp
