Figure 2. Schematic representation of human FCGRT gene. Chromosome (chr) localization: chr19. Coding and non-coding regions are represented by gray or black boxes respectively. Hs02236230 and Hs02001837 primers used in PCR assays are represented by a black line and probe used in Southern-blot is represented by a dashed line. Exons are identified by box numbers and length in nucleotides. 5′ or 3′UTR: 5′ or 3′ untranslated region, SP: signal peptide, α: α domain 1, 2 and 3; TM: transmembrane region; IC: intracytoplasmic region
