The subfamily of WNK protein kinases is composed of four human genes and is characterised by a typical sequence variation
within the conserved catalytic domain. Although most research has focussed on the role of WNK1, WNK3 and WNK4 in regulating
different ion transporters in both the kidney and extrarenal tissues, there is growing evidence for additional roles of WNK
kinases in various signalling cascades related to cancer. Here, we review the connection between WNK kinases and tumorigenesis
and describe existing experimental evidence as well as potential new links to major aspects of tumour biology. In particular,
we discuss their role in G1/S cell cycle progression, metabolic tumour cell adaptation, evasion of apoptosis and metastasis. 相似文献

Ataxia-ocular apraxia 2 (AOA2) was recently identified as a new autosomal recessive ataxia. We have now identified causative mutations in 15 families, which allows us to clinically define this entity by onset between 10 and 22 years, cerebellar atrophy, axonal sensorimotor neuropathy, oculomotor apraxia and elevated alpha-fetoprotein (AFP). Ten of the fifteen mutations cause premature termination of a large DEAxQ-box helicase, the human ortholog of yeast Sen1p, involved in RNA maturation and termination. 相似文献
