Characterisation of membrane protein ubiquitination by MARCH ligases

Grant number: DP160103134 | Funding period: 2016 - 2018



The goal of the project is to understand how a family of enzymes called MARCHs regulate expression and localisation of immunoregulatory receptors within cells by post-translational addition of a small protein tag called Ubiquitin. The aims are to decipher the ubiquitination patterns produced by the MARCHs; identify the E2 ligases used by the MARCHs to produce distinct Ub codes; and apply a new proteomic pipeline to identify novel representative MARCH substrates in mice deficient in six different MARCHs. It is anticipated the project will reveal novel insights into a fundamental cell biological process of major significance for regulation of protein expression and trafficking in cells of the ..
