An alternatively spliced exon encodes a cysteine-rich domain highly homologous to a repetitive sequence of thyroglobulin ispublished: pub subjects: ddc-570 divisions: i-706000 keywords: invariant chain gene, class II histocompatibility antigens , alternative-splicing , hyroglobulin , antigen processing abstract: The gene for murine Ia-associated invariant (1i) chains (1131 and 1i41) was characterized by sequence analysis. The gene extends over - 9 kb and is organized in nine exons. Exon 1 encodes the 5' untranslated region and the cytoplasmic segment, exon 2 the membrane spaniing segment and adjacent amino acids and exons 3- 8 the extracytoplasmic portion of 1131. Putative promoter sequences were found upstream of the start of the coding sequence. Between exons 6 and 7 an additional, alternatively spliced exon 6b has been identified. This exon is spliced into the mRNA coding for the li-related Ii41 protein. Exon 6b encodes a cysteine-rich domain of 64 amino acids. It shows a remarkably high homology to the repetitive elements in thyroglobulin, a precursor for thyroid hormone. Based on this homology, it is suggested that this domain (TgR) in Tg and in 1141 may play a role either in hormone formation or as a carrier in the transport of molecules (thyroid hormone or processed antigen respectively) between intracellular compartments. abstract_translated_lang: eng date: 1987 date_type: published id_scheme: DOI id_number: 10.11588/heidok.00008479 schriftenreihe_cluster_id: sr-2 schriftenreihe_order: 037 ppn_swb: 1352587823 own_urn: urn:nbn:de:bsz:16-opus-84799 language: eng bibsort: KOCHNORBERPRIMARYSTR1987 full_text_status: public publication: The EMBO Journal volume: 6 number: 6 pagerange: 1677-1683 citation: Koch, Norbert ; Lauer, Wolfgang ; Habicht, Jüri ; Dobberstein, Bernhard (1987) Primary structure of the gene for the murine Ia antigen-associated invariant chains (Ii).
