We have investigated the effects of the cell cycle on expression of Q4 mRNA. Q4, the gene encoding the Qb‐1 antigen, is transcribed in a wide variety of tissues, unlike many other non‐classical class I genes. We have compared the pattern of Q4 transcription in the cell cycle to classical class I, β‐2‐microglobulin and actin. We found that the pattern of Q4 RNA levels resembles that of the classical class I genes, consistent with the similarity of the 5′sequences of Q4 and K/D. Thus, Q4 mRNA accumulates during the cell cycle along with the total RNA, but does not show specific transcriptional enhancement. This is consistent with a function for Q4 similar to the classical K/D gene products.
