TTC28 (Tetratricopeptide Repeat Domain 28): TTC28 encodes a protein with a tetratricopeptide repeat domain, involved in the regulation of various cellular processes, including signal transduction and protein-protein interactions. Its precise biological functions are still under investigation, but mutations in TTC28 have been associated with predispositions to certain types of cancer, indicating its potential role in tumor suppression and cellular homeostasis....
