Webb22 feb. 2011 · The KIR gene cluster comprises up to 17 highly homologous and closely linked genes and pseudogenes. The KIRs can be classified into two different groups: first, the inhibitory group is characterized by a long (L) intracytoplasmic tail and two or three extracellular immunoglobulin domains. WebbKIR has inhibition and activation according to its extracellular domain. The function of KIR can be inferred by the length of cytoplasmic region. Generally speaking, longer receptors are usually inhibitory, and shorter ones are active. The only exception to this rule is KIR2DL4, a unique activator that stimulates cytokine production.
