The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
Interferon-alpha/beta receptor, fibronectin type III Provide feedback
Members of this family adopt a secondary structure consisting of seven beta-strands arranged in an immunoglobulin-like beta-sandwich, in a Greek-key topology. They are required for binding to interferon-alpha .

This clan includes a diverse range of domains that have an Ig-like fold and appear to be distantly related to each other. The clan includes: PKD domains, cadherins and several families of bacterial Ig-like domains as well as viral tail fibre proteins. it also includes several Fibronectin type III domain-containing families.
The clan contains the following 63 members:A2M_N Alpha_adaptinC2 Big_1 Big_2 Big_3 Big_3_2 Big_3_3 Big_3_4 Big_4 Big_5 BiPBP_C BsuPI Cadherin Cadherin-like Cadherin_2 Cadherin_pro CARDB CHB_HEX_C CHB_HEX_C_1 ChitinaseA_N CHU_C Coatamer_beta_C COP-gamma_platf CopC DUF1034 DUF11 DUF1973 DUF2271 DUF4165 DUF4625 DUF916 EpoR_lig-bind Filamin FixG_C FlgD_ig fn3 Fn3_assoc He_PIG HYR IFNGR1 IL6Ra-bind Integrin_alpha2 Interfer-bind Invasin_D3 MG1 Mo-co_dimer Neurexophilin NPCBM_assoc PapD_N PKD PPC Qn_am_d_aIII REJ Rib SoxZ SprB SWM_repeat T2SS-T3SS_pil_N TIG Tissue_fac Transglut_C TRAP_beta Y_Y_Y
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the Interfer-bind domain has been found. There are 57 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
