DOI: 10.1007/s40259-019-00333-w. JAK3 is the only member of the JAK family to have a cysteine (Cys909) in the ATP pocket. This residue has been targeted in JAK3 drug discovery, and one highly selective covalent JAK3 inhibitor is currently in phase 3 clinical trials against autoimmune diseases (Figure 3 D). Janus kinase 3 (JAK3) tyrosine kinase has a central role in the control of lymphopoiesis, and mutations in JAK3 can lead to either severe combined immunodeficiency or leukemia and lymphomas. JAK3 associates with the common gamma chain (γc) receptor and functions in a heteromeric signaling pair with JAK1.

Therefore, great efforts have been made for the development of JAK3 inhibitors, but developing selective JAK3 inhibitors remains a great challenge because of the high sequence homology with other kinases. 2019-01-30 Jakovlev Jak-3 (ven.

identiﬁed in JAK3, which cause severe combined immune deﬁciency (SCID); a disease resulting a depletion of B-cells and complete loss of T- and NK-cells [11,12]. A majority of the pathogenic mutants clusters in JH2 highlighting the regulative role of the domain [10]. The most common mutation, JAK2 V617F also resides in JH2.

JAK3 associates with the common gamma chain (γc) receptor and functions in a heteromeric signaling pair with JAK1. In IL-2 signaling JAK1 is the effector kinase for STAT5 phosphorylation but the precise JAK3, together with its dimerization partner JAK1, has an important role in maintaining immune homeostasis. JAK3 binds to the common γ c receptor, which drives the development of T cells, regulates the growth of B cells, and activates NK cell proliferation, among other functions [118,119,120]. on JAK2 and JAK3 found that loss of JH2 was also associated with.

In fact, JAK3/IL-7R/γ c mutations cover the majority of all SCID cases: JAK3 mutations account for approximately 10–18% of heritable SCID, IL-7R < 10%, and γ c 25–46% . Although JAK3 SCID-associated mutations are found in all JAK domains, the majority is located either in JH2 or the FERM domain . identiﬁed in JAK3, which cause severe combined immune deﬁciency (SCID); a disease resulting a depletion of B-cells and complete loss of T- and NK-cells [11,12].
