Figure 1. Structural Modifications for the Creation of Δ41-52 Human Prolactin.

Figure 1

Three dimensional structure of hPRL with helices 1 through 4 shown in blue, cyan, green, and red, respectively. The deleted residues (41-52) are indicated by the black backbone. The lower panel shows a section of the aligned sequences of human growth hormone and prolactin. The underlined residues are not present in the 20 kDa form of hGH and have been deleted in Δ41-52 hPRL.
