**Background of RASL12 Recombinant Protein**
RASL12 (RAS-like family member 12) is a member of the RAS superfamily of small GTPases, which regulate diverse cellular processes, including signal transduction, proliferation, and differentiation. Unlike classical RAS oncoproteins (e.g., HRAS, KRAS), RASL12 lacks canonical driver mutations linked to cancer but shares conserved structural features, such as GTP-binding domains and effector interaction regions. Its exact biological role remains less characterized compared to other RAS family members, though emerging studies suggest involvement in transcriptional regulation, cell cycle control, and stress response pathways.
RASL12 is expressed in various tissues, with higher levels observed in the brain, testis, and certain tumors. It localizes to both the nucleus and cytoplasm, hinting at dual roles in nuclear signaling and cytoplasmic processes. Research indicates that RASL12 may interact with proteins like Casein Kinase 2 (CK2) and influence pathways such as p53-mediated apoptosis or Wnt/β-catenin signaling, though mechanistic details are still under investigation. Dysregulation of RASL12 has been tentatively associated with neurological disorders and cancer progression, though causal links require validation.
Recombinant RASL12 protein is engineered for *in vitro* studies to dissect its molecular functions, post-translational modifications, and interactions. Produced via bacterial or mammalian expression systems, it often includes tags (e.g., His-tag) for purification and detection. Applications range from enzymatic assays (GTPase activity) to structural studies (X-ray crystallography) and drug screening. Current research focuses on clarifying its physiological and pathological roles, particularly its potential as a therapeutic target or biomarker in diseases like glioblastoma or prostate cancer.
Despite progress, RASL12’s full functional spectrum and regulatory networks remain enigmatic, necessitating further exploration to unlock its biological and clinical relevance.
