Prolactin is a protein hormone that, among other things, enables mammals to produced milk. Prolactin is secreted from cells in the pituitary gland in response to eating, mating, ovulation, and nursing. a. Prolactin is encoded by the PRL A segment of the PRL gene and its regulatory regions are shown below. The +1 site (*) and part of the promoter (#) of PRL are indicated.

Prolactin is a protein hormone that, among other things, enables mammals to produced milk. Prolactin is secreted from cells in the pituitary gland in response to eating, mating, ovulation, and nursing. a. Prolactin is encoded by the PRL A segment of the PRL gene and its regulatory regions are shown below. The +1 site (*) and part of the promoter (#) of PRL are indicated.

Using the mRNA you transcribed in part a, what are the first 8 amino acids of prolactin that are translated? cis face trans face MTOC Rough ER Golgi complex Cell membrane c. In what organelle is prolactin glycosylated? What motor protein would be used to transport prolactin from the rough ER to this organelle? d. Where does exocytosis occur? What motor protein would be used to transport prolactin from the site of its glycosylation to the site of its exocytosis? e. If this cell was stained with an antibody specific for y (gamma) tubulin, where would we expect to see the cell stained in this immunohistochemistry experiment?
