unusual facts about tyrosine kinase


Personalized medicine

Tyrosine kinase inhibitors such as imatinib (marketed as Gleevec) have been developed to treat chronic myeloid leukemia (CML), in which the BCR-ABL fusion gene (the product of a reciprocal translocation between chromosome 9 and chromosome 22) is present in >95% of cases and produces hyperactivated abl-driven protein signaling.


Estrogen receptor

In addition, some ER may associate with cell membranes by attachment to caveolin-1 and form complexes with G proteins, striatin, receptor tyrosine kinases (e.g., EGFR and IGF-1), and non-receptor tyrosine kinases (e.g., Src).

Hypereosinophilic syndrome

A proportion of patients have a mutation involving the PDGFRA and FIP1L1 genes on the fourth chromosome, leading to a tyrosine kinase fusion protein.

TEL-JAK2

The oligomerisation domain of the TEL protein (also called ETV6) becomes juxtaposed to the tyrosine kinase domain of JAK2, and as result the TEL-JAK2 displays constitutive kinase activity.

Congenital myasthenic syndrome

This pathway consists of agrin, muscle-specific tyrosine kinase (MuSK), acetylcholine receptors (AChRs) and the AChR-clustering protein rapsyn, encoded by the RAPSN gene.

Gastrointestinal stromal tumor

Most GIST cells with wildtype (i.e. not mutated) c-kit instead have a mutation in another gene, PDGFR-α (platelet derived growth factor receptor alpha), which is a related tyrosine kinase.

Huntingtin-associated protein 1

This gene encodes a protein that interacts with huntingtin, with two cytoskeletal proteins (dynactin and pericentriolar autoantigen protein 1), and with a hepatocyte growth factor-regulated tyrosine kinase substrate (HGS).

Marginal zone B-cell

In specimens where the tyrosine kinase for Pyk-2 has been knocked-out, marginal zone B-cells will fail to develop while B-1 cells will still be present.

MiR-338

miR-338 is located in an intronic region within the gene for apoptosis-associated tyrosine kinase (AATK).

Phosphatidylinositol 5-phosphate

In T-cells, two “downstream of tyrosine kinase” proteins DOK1 and DOK2 are proposed as PtdIns5P-binding proteins and effectors.

Quizartinib

Specifically, Quizartinib selectively inhibits class III receptor tyrosine kinases, including FMS-related tyrosine kinase 3 (FLT3/STK1), colony-stimulating factor 1 receptor (CSF1R/FMS), stem cell factor receptor (SCFR/KIT), and platelet derived growth factor receptors (PDGFRs).
