KRAS plays a critical role in regulating cell growth and division. KRAS mutations are common in many types of solid tumors, including lung, colon, and pancreatic cancers, and are associated…
The KRAS oncoprotein is a GTPase and an essential mediator of intracellular signaling pathways. KRAS oncoprotein regulates tumor cell growth and survival. However, KRAS also is the most frequently mutated…
Rapidly accelerated fibrous sarcoma (RAF) kinases are a family of three serine/threonine-specific protein kinases associated with retroviral oncogenes. They play key roles in several cellular processes, including cell cycle progression,…
Src-homology-2-containing protein tyrosine phosphatase 2 (SHP2), encoded by the PTPN11 gene, is a classical nonreceptor protein tyrosine phosphatase (PTP). SHP2 is a ubiquitous protein tyrosine phosphatase with a relatively conserved…
Repotrectinib is a potent ROS1 (IC50=0.07 nM) and TRK (IC50=0.83/0.05/0.1 nM for TRKA/B/C) inhibitor. The IC50 values are 0.83/0.05/0.1 nM for TRKA/B/C, respectively. Repotrectinib potently inhibits WT ALK (IC50=1.01 nM). Repotrectinib inhibits mutant ALKs. It inhibits…
The cold shock protein Y-box binding protein-1 (YB-1) is a multifunctional protein. It shows relations in cell proliferation, survival, and stress response. Through translation and transcription of key proteins and…
Protein Phosphatase 2A (PP2A) is a serine/threonine phosphatase. It regulates multiple signaling cascades implicated in cancer progression, including downstream effectors of KRAS. Inhibition of PP2A contributes to oncogenesis in multiple…
Protein phosphatase 2A (PP2A) comprises a family of serine/threonine phosphatases, minimally containing a well-conserved catalytic subunit. PP2A plays a prominent role in the regulation of specific signal transduction cascades. Additionally,…
KRAS functions as a molecular switch, cycling between inactive (GDP-bound) and active (GTP-bound) states to transduce extracellular signals via cell-surface receptors. KRAS signaling occurs through engagement with effector proteins that…
ERK1 and ERK2 are related protein-serine/threonine kinases that participate in the Ras-Raf-MEK-ERK signal transduction cascade. This cascade participates in the regulation of a large variety of processes. It includes cell…
