Prolactin receptor (PRLR)

This is a receptor for the anterior pituitary hormone prolactin (PRL). Acts as a prosurvival element for spermatozoa by inhibiting sperm capacitation through suppression of SRC kinase stimulation and activation of AKT.

Isoform 4 is unable to transduce prolactin signaling. Isoform 6 is unable to transduce prolactin signaling.
