Description:
The technique of whole-genome polymerase chain reaction was used to study the DNA binding properties of the product of the wt1 gene. The zinc finger region of this gene is alternatively spliced such that the major transcript encodes a protein with three extra amino acids between the third and fourth fingers. The minor form of the protein binds specifically to DNA. It is now shown that the major form of wt1 messenger RNA encodes a protein that binds to DNA with a specificity that differs from that of the minor form. Therefore, alternative splicing within the DNA binding domain of a transcription factor can generate proteins with distinct DNA binding specificities and probably different physiological targets.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bickmore, W A -- Oghene, K -- Little, M H -- Seawright, A -- van Heyningen, V -- Hastie, N D -- New York, N.Y. -- Science. 1992 Jul 10;257(5067):235-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Human Genetics Unit, Western General Hospital, Edinburgh, Scotland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1321494" target="_blank"〉PubMed〈/a〉
