Bio

Ciliary length and regulation are dictated by intraflagellar transport (IFT) which transports building materials into cilia to regulate assembly. Recent research has revealed multiple molecular targets in the Mitogen Activated Protein Kinase (MAPK) pathway that regulate ciliary length in many different types of cells from photoreceptors to C. elegans sensory neuron cilia. However, the mechanism that connects how MAPK regulates this function is unclear. Previously, our lab has found that BCI, [(E)-2-benzylidine-3-(cyclohexylamino)-2,3-dihydro-1H-inden-1-one], a vertebrate MAP Kinase Phosphatase 3 inhibitor, increases phosphorylated MAPK, shortens flagella, and prevents regeneration of full-length flagella in Chlamydomonas reinhardtii. The goal of my research project is to use BCI to identify more molecular targets in the MAPK pathway and ultimately put together a mechanism for its relation to ciliary length regulation.
