Pim1 is involved in cell cycle progression, apoptosis, transcriptional activation and signaling 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. Chk1 or checkpoint kinase 1 phosphorylates variety of proteins resulting in activation of DNA damage checkpoint and more[2]. Chk2 or checkpoint kinase 2 has a role in cell cycle arrest and apoptosis by DNA damage [3]. Plk1 or Polo-like kinase 1 phosphorylates variety of proteins affecting cell entry into mitosis, centrosome maturation, spindle assembly and cytokinesis[4]. Plk3 or Polo-like kinase 3 becomes phosphorylated after DNA damage or mitotic spindle disruption [5]. Haspin phosphorylates histone H3 and thus affects mitosis [6]. mTOR or mechanistic target of rapamycin signaling influences longevity and aging [7]. LRRK1, LRRK2 or leucine-rich repeat kinase phosphorylate Rab proteins [8]. Relevance Pim1 is a progression marker in diffuse large B-cell lymphoma[9]. Disease Pim-1 plays a pivotal role in several tumor relevant signaling pathways and is relevant to colon carcinoma[10]. Structural highlights Pim1 is phosphorylated on serine 261 (PSer). The [11].
