Overview

Spermatogenesis-associated protein 31 subfamily H member 1 (SPATA31H1) is a human protein-coding gene found on chromosome 2, encoding a nuclear and exosomal protein. It is a member of the rapidly evolving SPATA31 gene family, originally linked to spermatogenesis, but in humans it has acquired new domains and functions, notably in sensing and repairing UV-induced DNA damage. Overexpression of SPATA31 family members can cause premature cellular senescence by disturbing aging-related pathways, particularly through its involvement in regulated cell cycle and DNA repair. Naturally occurring lower copy numbers of SPATA31 appear to be associated with increased human longevity. While variants in this gene have been implicated in metabolic conditions and are broadly expressed, SPATA31H1 is not currently classified as a therapeutic target, and little is known about its detailed biochemical properties or drug interactions.
