Gene Variant Descriptions | JAK3 A573V lies within the protein kinase domain 1 of the Jak3 protein (UniProt.org). A573V results in constitutive phosphorylation of Jak3, activation of downstream Stat5 and Erk, is transforming in cultured cells (PMID: 18755984, PMID: 29046866, PMID: 28284718), and induces T-cell acute lymphoblastic leukemia in mouse models (PMID: 25193870). |
