Solute carrier family 45 member 3 (SLC45A3), also known as prostate cancer-associated protein 6 or prostein, is a protein that in humans is encoded by the SLC45A3 gene. SLC45A3 is an androgen-regulated gene and a prostate specific marker expressed in prostatic glandular cells. SLC45A3 is the second most common gene fusion partner in prostate cancers. SLC45A3-ERG and SLC45A3-ELK4 fusion transcripts have been detected in prostate cancer. Loss of prostein expression in SLC45A3-ERG tumors are significantly associated with high Gleason scores and poor clinical outcomes. Prostein immunoreactivity is seen in the majority of primary and metastatic prostate carcinomas. Staining for prostein in conjunction with PSA improves identification of prostatic origin in unknown primary lesions, when compared against prostein or PSA staining alone.

Immunohistochemical analysis of paraffin-embedded human prostate tissue using anti-SLC45A3 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA721018, 1/200) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
