Extracellular Matrix Proteome and Phosphoproteome of Potato Reveals Functionally Distinct and Diverse Canonical and Non-Canonical Proteoforms.

ABSTRACT: The extracellular matrix (ECM) has a molecular machinery composed of diverse proteins and proteoforms that combine properties of tensile strength with extensibility exhibiting growth-regulatory functions and self- and non-self-recognition. The identification of ECM proteoforms is the prerequisite towards a comprehensive understanding of biological functions accomplished by the outermost layer of the cell. Regulatory mechanisms of protein functions rely on post-translational modifications, phosphorylation in particular, affecting enzymatic activity, interaction, localization and stability. To investigate the ECM proteoforms, we have isolated the cell wall proteome and phosphoproteome of a tuberous crop, potato (Solanum tuberosum). LC-MS/MS analysis led to the identification of 38 proteins a
