Research Interests
Protein tyrosine kinases (PTKs) are cellular enzymes which catalyze phosphotransfer from ATP to tyrosine residues in proteins. The human genome encodes 90 tyrosine kinases, the majority of which are directly associated (by overexpression or mutation) with defects in cell proliferation and/or differentiation, resulting in cancer.
A current research effort in my laboratory is to understand tyrosine kinase biology in zebrafish. We have recently published the complete zebrafish tyrosine kinome highlighting their phylogenetic relationships and unique sequence features, using profile hidden markov models. We are studying the expression and role of zebrafish homologs of BRK. Understanding tyrosine kinase dysregulation and cancer in zebrafish is a likely outcome of this work.
A connected research area in my lab is based on the hypothesized regulation of tyrosine kinases by non-catalytic domain interactions with their splice-variants. We are testing this hypothesis by studying the regulation of BRK (breast tumour kinase) signalling by one of its splice-variants, and its effect on cell proliferation. The relevance of such a mechanism in cancer initiation and progression will be studied using human tissue samples.
