Area of Science:

  • Molecular Biology
  • Genetics
  • Gene Expression

Context:

  • The intersectin (ITSN) gene, located on human chromosome 21 (q22.1-22.2), plays a role in cellular processes.
  • Understanding the full spectrum of ITSN gene transcripts is crucial for elucidating its biological functions.

Purpose:

  • To identify and characterize novel human and mouse cDNAs homologous to the ITSN gene.
  • To investigate the alternative splicing patterns of ITSN gene transcripts in different tissues.

Summary:

  • New human and mouse cDNAs homologous to the intersectin (ITSN) gene were identified.
  • Analysis revealed diverse pre-mRNA splicing events in human and mouse ITSN transcripts.
  • Specific splice variants, including those with alternative SH3C domains or exon deletions leading to frame shifts, were detected in various tissues.
