WebApr 11, 2024 · An altered or improperly regulated secretion of those agents could initiate a disease condition or worsening an existing one. Peptide hormones are processed and secreted as small proteins that signal via membrane receptors and play important roles in virtually every aspect of physiology. WebA role for a predicted PMO, HAM-7, is required for chemotropic interactions and functions through the cell wall integrity (CWI) MAP kinase signaling pathway in filamentous fungi. Strains lacking ham-7 fail to undergo cell fusion and thus lack an interconnected hyphal network. The ham-7 gene and its relatives form a unique clade among PMOs in fungi.
