    regulatory sequence Promoter
    text structure
  • first exon of CHL2 contains 5prime UTR sequences, the translation initiation codon, and a cleavable N-terminal signal peptide at positions 1–25 (Oren 2004)
  • exons 2 and 3 encode for CR1, and exons 4 and 5 encode for CR2. CR3 is encoded by one exon, exon 8 (Oren 2004)
  • MAPPING cloned Y linked N status provisional
    RNA
    TRANSCRIPTS type messenger
    text
  • variants encoding proteins with or without an N-terminal signal peptide, suggesting the existence of extracellular and intracellular isoforms
  • distinct CHL2 isoforms that differ in their C-termini, the presence of a signal peptide, and the content of their CR domains (Oren 2004)
