Threonine kinase AKT

The V-Akt murine thymoma viral oncogene (AKT) 1 (E17K) is a subfamily of serine/threonine protein kinases that affects the survival, proliferation, and invasion of cancer cells. The clinicopathological features and frequencies in Asian populations with AKT1 mutations in breast and endometrial cancers are unclear.

Akt (PKB) is a serine threonine protein kinase downstream of the phosphoinositide 3-kinase (PI3K) pathway. In mammals, Akt is ubiquitously expressed and is associated with regulation of cellular proliferation, metabolism, cell growth and cell death. Akt has been widely studied for its central role in physiology and disease, in particular cancer where it has become an attractive pharmacological target.

Akt is a serine/threonine kinase that mediates signaling downstream of tyrosine kinase receptors like the type I insulin-like growth factor receptor (IGF-IR). In fact, we have previously shown that mammary tumors induced by elevated expression of the IGF-IR are associated with hyperactivation of Akt.

The serine-threonine kinase AKT1 plays essential roles during normal mammary gland development as well as the initiation and progression of breast cancer. AKT1 is generally considered a ubiquitously expressed gene, and its persistent activation is transcriptionally controlled by regulatory elements characteristic of housekeeping gene promoters.

Aberrant AKT activation is prevalent across human cancer lineages, providing an important therapeutic target. AKT comprises three isoforms that mediate critical non-redundant, even opposing functions in cancer pathophysiology.

Akt là một loại enzym serin/threonin protein kinase có vai trò quan trọng trong chu trình sống và tăng sinh của tế bào. Việc ức chế vùng allosteric giúp giữ enzym ở cấu dạng bất hoạt. Nghiên cứu được xây dựng để tìm kiếm những khung cấu trúc mới có tiềm năng ức chế allosteric Akt1 từ các nguồn dữ liệu tối ưu.

HAND2/dHAND is a basic helix-loop-helix transcription factor expressed in the heart and neural crest derivatives during embryogenesis. Although dHAND is essential for branchial arch, cardiovascular and limb development, its target genes have not been identified. The regulatory mech-anisms of dHAND function also remain relatively unknown. Here we report that Akt/PKB, a serine/threonine protein kinase involved in cell survival, growth and differ-entiation, phosphorylates dHAND and inhibits dHAND-mediated transcription....

The mechanisms underlying increased cardioprotection in younger female mice are unclear. We hypothesized that serine-threonine protein kinase (protein kinase B; Akt) triggers a metabolic gene switch (decreased fatty acids, increased glucose) in female hearts to enhance mitochondrial bio-energetic capacity, conferring protection against oxidative stress.

PI3K is a heterodimeric lipid kinase that catalyses the conversion of phosphatidylinositol bisphosphate (PIP2) to phosphatidylinositol trisphosphate (PIP3), which acts as a plasma membrane docking site for proteins that contain a pleckstrin homology (PH) domain. These include the serine/threonine kinases Akt and PDK1 that are key downstream effectors of PI3K action (Fig. 80-2). The PI3K pathway is activated in 30–40% of human cancers and is thought to play a critical role in tumor cell survival, proliferation, growth, and glucose utilization.
