PERK (Protein kinase R (PKR)-like endoplasmic reticulum kinase) is a type I endoplasmic reticulum transmembrane protein. Generally, PERK contains a stress-sensing domain facing the endoplasmic reticulum lumen and a cytosolic…
XIAP is a protein that prevents apoptosis. XIAP is a member of apoptosis protein family (IAP) inhibitors. Specifically, IAP blocks cell death in vitro and in vivo by inhibiting different…
Phosphoinositide 3-kinases (PI3Ks), also called phosphatidylinositol 3-kinases, are a family of enzymes involved in cellular functions. Class I PI3K enzymes consist of four distinct catalytic isoforms, PI3Kα, PI3Kβ, PI3Kδ and…
Bruton's tyrosine kinase (abbreviated Btk or BTK) is a tyrosine kinase that is encoded by the BTK gene in humans. BTK, a kinase expressed in B cells and bone marrow…
The Raf family consists of three members: A-Raf, B-Raf, and Raf-1. Ras/RAF/MEK extracellular signal-regulated kinase (ERK) pathway is relevant to the control of many basic cellular processes, including proliferation, survival,…
Receptor tyrosine kinases (RTKs) are high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones. Specifically, RTKs are part of a larger family of protein tyrosine kinases. RTKs…
DNA topoisomerase I (Top1) is a DNA unwinding protein and the specific target of the camptothecin class of chemotherapeutic drugs. Top1 binds supercoiled DNA, nicks a DNA strand allowing its…
mTOR is a member of the phosphatidylinositol 3-kinase related kinase family of protein kinases. Meanwhile, mTOR is linked to other proteins and serves as the core component of two different…
The myeloproliferative neoplasms (MPNs) are a group of related clonal diseases probably arising from hematopoietic progenitor or stem cells. Patients with MPNs have an increased risk of thrombotic and bleeding…
Cereblon (CRBN) is a key protein in autosomal recessive nonsyndromic mental retardation. Specifically, it plays an intermediary role in helping immunomodulatory drugs play their immunomodulatory and tumor-killing roles. Besides, CRBN…
