CCR5 that plays a role in inflammatory response. Unfortunately, this protein is also a key to human immunodeficiency virus (HIV) infection. The virus binds to a loop of the CCR5 protein and then enters the cell. Some people have an allele called Δ32 at the CCR5 locus in which 32 bp are deleted. The missing part of the gene codes for the loop in the protein to which the virus attaches. Which statements is true for CCR5?
