Hypothesis
The organization of the FAK gene and its potential to generate multiple isoforms are not well understood.
Conclusion
The alternative coding exons 13, 14, 16, and 31 are highly conserved in vertebrates and their inclusion in mRNA is tightly but independently regulated.
Supporting Evidence
- FAK is a non-receptor tyrosine kinase critical for processes ranging from embryo development to cancer progression.
- Gene duplication probably occurred in deuterostomes after the echinoderma embranchment, leading to the evolution of PYK2.
- Comparison of mouse and human FAK genes revealed multiple combinations of conserved and non-conserved 5'-untranslated exons.
Takeaway
FAK is a protein that helps cells stick together and move. This study found that different parts of the FAK gene can be included or excluded in a way that is important for how it works in different tissues.
Methodology
The study used sequence analysis and RT-PCR to examine the existence and conservation of various putative variants of FAK transcripts.
Limitations
The study does not address the functional implications of the non-conserved alternative splicing events.
