Function
Proto-oncogene serine/threonine-protein kinase are a subset of serine/threonine-protein kinase which upon mutating cause cancer development.
Proto-oncogene serine/threonine-protein kinase (Pim1) is the provirus integration site for Moloney murine leukemia virus 1[1]. Pim1 is involved in cell cycle progression, apoptosis, transcriptional activation and signalling pathways. Pim1 phosphorylates and inhibits proapoptotic proteins. For details see Student Project 6 for UMass Chemistry 423 Spring 2015. See also Oncogenes & Tumor Suppressor Genes.
- b-Raf is related to retroviral oncogenes and participates in cellular signal transduction. B-Raf domains include the kinase domain - residues 444-721 and Ras-binding domain - residues 153-237. Mutated B-Raf was found in some human cancers[2].
See more in B-RAF with PLX4032; Mitogen-activated protein kinase cascade.
- c-Raf is part of the MAPK pathway. c-Raf domains include the kinase domain - residues 323-618, cysteine-rich domain – residues 136-187 and Ras-binding domain - residues 51-132. Mutations of c-Raf are possible causes of Noonan syndrome[3]. For details on c-Raf see Molecular Playground/C-Raf and Mitogen-activated protein kinase cascade.
- a-RAF stabilizes B-RAF:C-RAF complexes and thus regulates cell signalling[4].
- AKT1 has a role in tumor progression[5].
- AKT2 is critical to control of glucose metabolism by insulin [6].
- AKT3 is required for biogenesis of mitochondria [7].
- LRRK1, LRRK2 or leucine-rich repeat kinase phosphorylate Rab proteins [8].
- RIP regulates apoptosis[9].
- Ulk1, Ulk2 play a role in activating autophagy in mammals[10].
- Hipa phosphorylates Glu-tRNA synthetase causing bacterial antibiotic persistence [11].
Relevance
Pim1 is a progression marker in diffuse large B-cell lymphoma[12].
Disease
Pim-1 plays a pivotal role in several tumor relevant signaling pathways and is relevant to colon carcinoma[13].
Structural highlights
Pim1 is phosphorylated on serine 261 (PSer). The consensus peptide (pimtide) ARKRRRHPSGPPTA binds strongly to Pim1[14]. Water molecules are shown as red spheres.
