Research

Research Summary:  The Weiler laboratory is interested in eukaryotic chromosome structure and function, and more specifically the role of epigenetic mechanisms.  Drosophila melanogaster (the fruit fly) has played a leading role in the field of chromosome biology, and is the organism of choice for our research laboratory as well as many others studying various aspects of chromosome behavior.  With D. melanogaster we have a powerful toolbox of genetics, molecular genetics and cytology at our fingertips and resources that include a sequenced genome, a large public collection of mutant and transgenic strains and a friendly research community.

Our long term goal is to better understand the molecular mechanisms by which nonhistone chromosomal proteins regulate genome activity in Drosophila.  To this end, we are studying two proteins:  D1 and the E(var)3-9 protein.  The D1 protein was originally identified biochemically as a DNA-binding protein that has high affinity for AT-rich satellite DNAs within heterochromatin.  We are taking a genetic approach to elucidate the function of D1.  Our current hypothesis is that D1 regulates gene expression as an architectural transcription factor.  The E(var)3-9 gene was originally identified via dominant mutations that enhanced position effect variegation of the In(1)wm4 allele.  The E(var) class of genic modifiers is proposed to encode proteins that promote a euchromatic chromatin structure and/or antagonize heterochromatic chromatin structure.  The results of our analyses support this hypothesis.  The cloning and sequence analysis of the E(var)3-9 gene revealed that it encodes a zinc finger protein, suggestive of DNA-binding activity.
