Expression sequence of proteins in rods on the edge of the PCA. Cone opsins are included for comparison. Note the early group of NRL, AIPL1, NR2e3, recoverin and IRBP appear 3-5 weeks before rod opsin. The phototransduction associated proteins, peripherin, rod arrestin, and NaCh, are expressed at the same time or soon after rod opsin with TULP the last to appear in rods.
