CX or Cx may refer to:
CXorf66 also known as Chromosome X Open Reading Frame 66, is a 361aa protein in humans that is encoded by the CXorf66 gene.
Chemokine receptor CXCR3 is a Gαi protein-coupled receptor in the CXC chemokine receptor family. Other names for CXCR3 are G protein-coupled receptor 9 (GPR9) and CD183. There are three isoforms of CXCR3 in humans: CXCR3-A, CXCR3-B and chemokine receptor 3-alternative (CXCR3-alt).
C-X-C motif chemokine 10 (CXCL10) also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10 is an 8.7 kDa protein that in humans is encoded by the CXCL10 gene.
CXorf49 is a protein, which in humans is encoded by the gene chromosome X open reading frame 49(CXorf49).
CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family.
Fractalkine also known as chemokine (C-X3-C motif) ligand 1 is a protein that in humans is encoded by the CX3CL1 gene.
CX3C chemokine receptor 1 (CX3CR1) also known as the fractalkine receptor or G-protein coupled receptor 13 (GPR13) is a protein that in humans is encoded by the CX3CR1 gene.
