Which of the following is NOT a property shared by both CD4 and CD8?
A)Binds to nonpolymorphic regions of MHC molecules
B)Cytoplasmic tail associates with the Src family kinase Lck
C)Is a member of the Ig superfamily
D)Functions as a coreceptor for αβ TCRs
E)Is expressed on the majority of mature blood T cells

Question

Quizplus · Accepted Answer

CD4 is expressed on the majority (~65%) of mature blood T cells, whereas CD8 is expressed on a minority (~35%). Both CD4 and CD8 are transmembrane glycoprotein members of the Ig superfamily, both serve as MHC-binding coreceptors for the T cell receptor, and both participate in early signal transduction events via cytoplasmic tail binding of the Src family tyrosine kinase Lck
