General description
Anti-Keratin 19 Antibody detects endogenous levels of total Keratin 19 protein.
Cytokeratin 19 (KRT19) is a cytoplasmic intermediate filament protein with a α-helical central domain. It belongs to the acidic type I cytokeratin family of proteins (KRTs). This gene is mapped to human chromosome 17q21.
Immunogen
The antiserum was produced against synthesized peptide derived from human Keratin 19.
Immunogen Range: 231-280
Immunogen Range: 231-280
Biochem/physiol Actions
Cytokeratin 19 (KRT19) plays a major role in structural rigidity and multipurpose scaffolds. Overexpression of this gene in various cancers may participate in tumorigenic transformation. It may modulate signaling pathways and mediate cell apoptosis, cell cycle arrest, invasion and metastasis. KRT19 plays a vital role in the cancer stemness of hepatocellular carcinoma (HCC).

Pancreatic acinar cells have high plasticity and can transdifferentiate into ductal-like cells. This acinar-to-ductal metaplasia (ADM) contributes to tissue maintenance but may also contribute to the premalignant transformation that can eventually progress to pancreatic ductal adenocarcinoma (PDAC). Macrophages are key
