γ-glu-ε-lys

γ-Glu-Lys (L-γ-Glutamyl-L-lysine) is a γ-glutamyl dipeptide.

DNA polymerase α subunit B (POLA2) (22-30) is a peptide segment derived from POLA2, a protein that plays a crucial role in the initiation of DNA replication and the repair of DNA double-strand breaks (DSB) as part of the DNA polymerase α complex.

Epsilon-(gamma-glutamyl)-lysine is an N(6)-acyl-L-lysine derivative that establishes cross-links between extracellular matrix (ECM) components through the catalytic activity of the enzyme tissue transglutaminase (tTg), and Epsilon-(gamma-glutamyl)-lysine has been implicated in the pathological remodeling of tissues in diseases such as non-diabetic kidney disease and in the progression of glaucoma filtration, rendering it a critical biomarker and mechanistic factor in extracellular matrix biology.
