SET domain-containing protein 5 mRNA (SETD5 mRNA) (SETD5 mRNA)

SET domain-containing protein 5 (SETD5) mRNA encodes a protein that serves as a critical transcriptional regulator and scaffold for chromatin-modifying complexes (UniProt, Q969Z0). The SETD5 protein interacts with the NCoR/SMRT corepressor complex and histone deacetylase 3 (HDAC3) to modulate gene expression patterns essential for normal neurodevelopment (Osipovich et al., 2016, Developmental Cell). Mutations in the SETD5 gene that lead to reduced mRNA levels or non-functional protein are a primary cause of autosomal dominant intellectual disability-23 (MRD23) and are frequently associated with autism spectrum disorder (NCBI Gene, ID: 55209). Conversely, the overexpression of SETD5 mRNA has been implicated in the progression and chemoresistance of various cancers, including pancreatic and lung adenocarcinoma, by promoting a stem-like cellular state (Sowd et al., 2021, Nature Communications). As a therapeutic target, SETD5 mRNA is being investigated for modulation via antisense oligonucleotides (ASOs) or RNA interference (RNAi) to downregulate its expression in oncogenic settings (PubMed, PMID: 32853556). Additionally, mRNA-based replacement strategies are a potential avenue for treating haploinsufficiency-related neurodevelopmental disorders. Precise control of SETD5 levels is necessary, as both deficiency and excess can lead to significant pathological outcomes.
