Protein Family Models

The cells at the periphery of the root cap are continuously sloughed off from the root into the mucilage, and are thought to be programmed to die [1].This family represents a conserved region approximately 60 residues in length within plant root cap proteins, which may be involved in the process.

This family consists of several plant proteins and includes RHO1, an interactor of the exocyst subunit Exo70A1 and has been shown to be required for seed coat mucilage deposition [1]. [1]. 20618910.

This entry represents a glycosyltransferase-like domain found in alkaline ceramidase TOD1 and the probable hexosyltransferase MUCI70 from Arabidopsis. MUCI70 is a predicted glycosyltransferase essential for the accumulation of seed mucilage, a gelatinous wall rich in unbranched rhamnogalacturonan I (RG I), and for shaping the surface morphology of seeds [1,2]. TOD1 is an endoplasmic reticulum ceramidase that catalyses the hydrolysis of ceramides into sphingosine and free fatty acids at alkaline pH (e.g. pH 9.5) [3,4]. [1]. 30228108.
