Background:

Basonuclin is a zinc-finger protein crucial for keratinocyte function.
Understanding the genetic basis of basonuclin is essential for cell biology research.

Purpose of the Study:

To clone and sequence the human basonuclin gene.
To determine the gene's chromosomal location and structural organization.
To investigate potential regulatory elements within the gene's flanking regions.

Main Methods:

Gene cloning and DNA sequencing techniques.
Chromosomal assignment studies.
Bioinformatic analysis of gene structure and regulatory sequences.

Main Results:

Related Experiment Videos

The human basonuclin gene was successfully cloned and sequenced.
The gene was assigned to chromosome 15.
The transcription unit spans approximately 29 kb, with five exons; zinc fingers are encoded by the final two exons.
The 5' flanking sequence and first exon are GC-rich and contain numerous CpG dinucleotides and Sp1 transcription factor binding sites.

Conclusions:

The structural characterization of the human basonuclin gene provides a foundation for further functional studies.
The identified regulatory elements suggest complex transcriptional control of basonuclin expression in keratinocytes.
