Neurospora crassa protein arginine methyl transferases are involved in growth and development and interact with the NDR kinase COT1.

ABSTRACT: The protein arginine methyltransferaseas (PRMTs) family is conserved from yeast to human, and regulates stability, localization and activity of proteins. We have characterized deletion strains corresponding to genes encoding for PRMT1/3/5 (designated amt-1, amt-3 and skb-1, respectively) in Neurospora crassa. Deletion of PRMT-encoding genes conferred altered Arg-methylated protein profiles, as determined immunologically. Δamt-1 exhibited reduced hyphal elongation rates (70% of wild type) and increased susceptibility to the ergosterol biosynthesis inhibitor voriconazole. In ▵amt-3, distances between branches were significantly longer than the wild type, suggesting this gene is required for proper regulation of hyphal branching. Deletion of skb-1 resulted in hyper conidiation (2-fold of the
