gp130LIF

gp130LIF, also known as the LIF receptor alpha subunit or CD115, is a type I transmembrane glycoprotein that plays a crucial role in cellular signaling. It is a member of the cytokine receptor superfamily and serves as a high-affinity binding protein for leukemia inhibitory factor (LIF). gp130LIF is expressed on a variety of cell types, including embryonic stem cells, neurons, hepatocytes, and hematopoietic progenitor cells. Upon binding of LIF, gp130LIF heterodimerizes with gp130, a common signal-transducing receptor subunit, to form a functional receptor complex. This complex then activates the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) signaling pathway, leading to diverse cellular responses. These responses include the maintenance of embryonic stem cell pluripotency, neuronal differentiation and survival, acute phase responses in the liver, and the regulation of hematopoiesis. The interaction between LIF and its receptor is critical for numerous developmental processes and maintaining tissue homeostasis. Dysregulation of this signaling pathway has been implicated in various diseases, including cancer and neurological disorders.
