Protein kinases have been the most heavily researched and targeted class of drug candidates in oncology, and they play a pivotal role in cellular signaling. This review examines Protein Serine Kinase H1 (PSKH1), which is an example of a member of the 'dark kinome' that is not extensively studied. PSKH1 recently emerged as a major component of cancer development. Functional RNAi screens demonstrated that PSKH1 enhances proliferation in both androgen-dependent and castration-resistant prostate cancer models. PSKH1's mechanism of action is distinct, as it has two major regulatory nodes: Calcium-dependent phosphorylation by Calmodulin activates it, and Reticulocalbin-3 inhibits PSKH1 through protein-protein interactions. Additionally, PSKH1 activates several pro-survivals signaling pathways (such as p38 MAPK) and regulates alternative splicing of pre-mRNAs in cancer. This review will summarize recent studies relating to the importance of PSKH1 as a potential therapeutic target for prostate cancer. This study discusses PSKH1's general biochemistry, its association with cancer, and the signaling pathways it regulates. Moreover, this study presents a multi-pronged approach linking how it can be inhibited therapeutically, including ATP-competitive and allosteric inhibition, protein- protein interaction displacement, protein degraders (PROTACs), and nucleic acid therapeutics. This study proposes that PSKH1 inhibition represents a novel treatment opportunity to simultaneously interfere with multiple oncogenic pathways and is expected to circumvent resistance and potentiate other treatments.
