Cardiotrophin-like cytokine factor 1 (CLCF1), also known as Novel Neurotrophin-1 (NNT-1) or B cell-stimulating factor-3 (BSF-3), is a protein that in humans is encoded by the CLCF1 gene. [5]
CLCF1 is a cytokine. It induces tyrosine phosphorylation of the IL-6 receptor common subunit glycoprotein 130 (gp130), leukemia inhibitory factor receptor beta, and the transcription factor STAT3. It has been implicated in the induction of IL-1 (via induction of corticosterone and IL-6) and serum amyloid A, and in B cell hyperplasia. CLCF1 is capable of B cell activation via gp130 receptor stimulation. [6]
CLCF1 is a cytokine belonging to the interleukin-6 (IL6) family. It is a secreted protein, found predominantly in lymph nodes and spleen, and contains 225 amino acids with a molecular mass of 22 kDa in its mature form. IL6 family members share similarity in gene structure and have a 4-helix bundle in their protein structure. CLCF1 is closely related to other proteins called cardiotrophin-1 and ciliary neurotrophic factor.
A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. Usually it is a secreted protein or a steroid hormone. Growth factors are important for regulating a variety of cellular processes.
Neurotrophin-3 is a protein that in humans is encoded by the NTF3 gene.
The activin A receptor also known as ACVR1C or ALK-7 is a protein that in humans is encoded by the ACVR1C gene. ACVR1C is a type I receptor for the TGFB family of signaling molecules.
Ciliary neurotrophic factor is a protein that in humans is encoded by the CNTF gene.
Interleukin-31 (IL-31) is a protein that in humans is encoded by the IL31 gene that resides on chromosome 12. IL-31 is an inflammatory cytokine that helps trigger cell-mediated immunity against pathogens. It has also been identified as a major player in a number of chronic inflammatory diseases, including atopic dermatitis.
Neurotrophin-4 (NT-4), also known as neurotrophin-5 (NT-5), is a protein that in humans is encoded by the NTF4 gene. It is a neurotrophic factor that signals predominantly through the TrkB receptor tyrosine kinase.
JAK1 is a human tyrosine kinase protein essential for signaling for certain type I and type II cytokines. It interacts with the common gamma chain (γc) of type I cytokine receptors, to elicit signals from the IL-2 receptor family, the IL-4 receptor family, the gp130 receptor family. It is also important for transducing a signal by type I (IFN-α/β) and type II (IFN-γ) interferons, and members of the IL-10 family via type II cytokine receptors. Jak1 plays a critical role in initiating responses to multiple major cytokine receptor families. Loss of Jak1 is lethal in neonatal mice, possibly due to difficulties suckling. Expression of JAK1 in cancer cells enables individual cells to contract, potentially allowing them to escape their tumor and metastasize to other parts of the body.
Interleukin 6 receptor (IL6R) also known as CD126 is a type I cytokine receptor.
Protease-activated receptor 4 (PAR-4), also known as coagulation factor II (thrombin) receptor-like 3, is a protein that in humans is encoded by the F2RL3 gene.
Nuclear factor of activated T-cells 5, also known as NFAT5 and sometimes TonEBP, is a human gene that encodes a transcription factor that regulates the expression of genes involved in the osmotic stress.
Interleukin 10 receptor, beta subunit is a subunit for the interleukin-10 receptor. IL10RB is its human gene.
Interleukin 11 receptor, alpha subunit is a subunit of the interleukin 11 receptor. IL11RA is its human gene.
TNF receptor-associated factor 4 (TRAF4) also known as RING finger protein 83 (RNF83) is a protein that in humans is encoded by the TRAF4 gene.
Tumor necrosis factor receptor superfamily member 12A also known as the TWEAK receptor (TWEAKR) is a protein that in humans is encoded by the TNFRSF12A gene.
Interleukin 17 receptor A, also known as IL17RA and CDw217, is a human gene.
Interleukin 21 receptor is a type I cytokine receptor. IL21R is its human gene.
Leucine-rich PPR motif-containing protein, mitochondrial is a protein that in humans is encoded by the LRPPRC gene. Transcripts ranging in size from 4.8 to 7.0 kb which result from alternative polyadenylation have been reported for this gene.
Cytokine receptor-like factor 1 is a protein that in humans is encoded by the CRLF1 gene.
Potassium intermediate/small conductance calcium-activated channel, subfamily N, member 1 , also known as KCNN1 is a human gene encoding the KCa2.1 protein.
FYVE, RhoGEF and PH domain-containing protein 2 (FGD2), also known as zinc finger FYVE domain-containing protein 4 (ZFYVE4), is a protein that in humans is encoded by the FGD2 gene.
