   G protein-coupled receptors (GPCRs) constitute a vast protein family that
   encompasses a wide range of functions (including various autocrine, para-
   crine and endocrine processes). They show considerable diversity at the
   sequence level, on the basis of which they can be separated into distinct
   groups. We use the term clan to describe the GPCRs, as they embrace a group
   of families for which there are indications of evolutionary relationship,
   but between which there is no statistically significant similarity in
   sequence [1,2]. The currently known clan members include the rhodopsin-like
   GPCRs, the secretin-like GPCRs, the cAMP receptors, the fungal mating
   pheromone receptors, and the metabotropic glutamate receptor family.
   
   The rhodopsin-like GPCRs themselves represent a widespread protein family
   that includes hormone, neurotransmitter and light receptors, all of
   which transduce extracellular signals through interaction with guanine
   nucleotide-binding (G) proteins. Although their activating ligands vary
   widely in structure and character, the amino acid sequences of the 
   receptors are very similar and are believed to adopt a common structural
   framework comprising 7 transmembrane (TM) helices [3-5].
   
   Chemokines are proteins that have important physiological and patho-
   physiological roles in a wide range of acute and chronic inflammatory
   processes [6]. Their sequences are similar and are characterised by a
   4-cysteine motif: the family can be divided according to whether the first 2
   Cys residues are adjacent (the C-C family), or separated by an intervening
   residue (the C-x-C family).
   
   The C-X-C chemokines IP10, Mig and I-TAC are upregulated in response to
   interferon-gamma and are potent chemoattractants for activated T cells
   [8,11]. All three chemokines have been found to activate the type 3 C-X-C
   chemokine receptor (CXCR3) [7,8]. CXCR3 is expressed in natural killer cells
   and activated T lymphocytes but not in resting T lymphocytes, B lymphocytes,
   monocytes or granulocytes [7]. CXCR3 also appears to be constitutively
   expressed on endothelial cells of medium and large blood vessels [9]. Upon
   binding to CXCR3, all three ligands cause mobilisation of intracellular
   calcium and chemotaxis. I-TAC, however, has a much higher affinity for the
   receptor and produces more potent effects than IP10 or Mig [8]. I-TAC
   appears to bind to two distinct sites on CXCR3: when the receptor is in the
   active conformation, all three ligands can bind, but I-TAC binds at an
   allotropic site, distinct from that of IP10 and Mig. By contrast, only I-TAC
   can bind to the uncoupled conformation of the receptor [10]. CXCR3 is also
   capable of binding a number of CC chemokines with moderate affinity. One of
   these, eotaxin, appears to act as a natural antagonist of the receptor [11].
  
   The main role of CXCR3 and its ligands appears to be the selective
   recruitment of effector T cells in both normal tissues and inflammation [8].
   CXCR3 may be involved in a number of T cell-mediated inflammatory diseases,
   such as autoimmune diseases, delayed-type hypersensitivity responses,
   certain viral diseases and transplant rejection. Upregulation of I-TAC in
   astrocytes and microglial cells by interferon suggests that it may also play
   a role in neuroinflammatory diseases, such as meningitis, encephalitis and
   multiple sclerosis [8]. IP10 has also been suggested to be involved in
   recruitment of inflammatory cells into the brain following ischaemic injury
   [12].
  
   CXCCHMKINER3 is a 9-element fingerprint that provides a signature for the
   type 3 C-X-C chemokine receptor. The fingerprint was derived from an initial
   alignment of 4 sequences: the motifs were drawn from conserved regions
   spanning the full alignment length, focusing on those sections that
   characterise the type 3 C-X-C chemokine receptors but distinguish them
   from other members of the chemokine receptor family - motifs 1-3 reside at
   the N-terminus; motif 4 spans the first cytoplasmic loop, leading into TM
   domain 2; motif 5 encodes the second cytoplasmic loop; motif 6 spans the
   C-terminal portion of TM domain 4; motif 7 lies in the second external loop;
   motif 8 lies in the third external loop, leading into TM domain 7; and motif
   9 resides at the C-terminus. A single iteration on SPTR39_15f was required
   to reach convergence, no further sequences being identified beyond the 
   starting set.
