Tissue distribution and cellular localization of PC1/3 mRNA in porcine tiss
ues were examined by ribonuclease protection assay and in situ hybridizatio
n. PC1/3 mRNA was detected mainly in the corpus luteum of pregnant sow and
brain. Within the ovary, PC1/3 and relaxin transcripts colocalized within l
arge luteal cells. Levels of PC1/3 transcripts in corpora lutea increased a
s gestation advanced, parallel with an observed increase in relaxin transcr
ipts. A role for PC1/3 in proprotein processing in the ovary is discussed.
