TGFBR1

(redirected from ALK5)

TGFBR1

A gene on chromosome 9q22 that encodes a transmembrane kinase of the TGFB receptor subfamily of Ser/Thr protein kinases, which forms a heteromer with type-II TGF-beta receptors and binds TGF-beta. This receptor/ligand complex phosphorylates proteins which enter the nucleus and regulate transcription of cell proliferation-related genes.

Molecular pathology
TGFBR1 mutations are associated with Loeys-Deitz aortic aneurysm syndrome.

Using a mouse model of cancer, they show that blocking the action of a signalling molecule called ALK5 makes tumour blood vessels even leakier for a short period of time, and this window of leakiness can be used to "open up" the tumour for more efficient delivery of drugs.
Blocking the ALK5 pathway may not only make chemotherapy far more effective in multiple cancers, but could also aid in efficient delivery of the many other therapies that rely on the bloodstream to carry them into a tumour.
Further, ALK5 blockade could assist in diagnosis as well as treatment; the imaging molecules used to light up tumours so that they can be seen by scanners might also be able to get in more easily if ALK5 were inactivated at the time of scanning.
According to reports in this field (25, 30, 31, 36), TGF-[beta] can signal through two type I receptors, ALK1 and ALK5, which display different affinities for TGF-[beta1].
