| Type: | Family | Name: | Protein trichome birefringence-like 28/30/ESKIMO 1 |
| Description: | Trichome birefringence-like (TBL) proteins are proposed to encode wall poly- saccharide specific O-acetyltransferases. This entry includes TBL28, TBL29 and TBL30. TBL29, also known as ESKIMO 1 (ESK1), is the only characterised one among the three of them. In Arabidopsis, ESK1 (AT3G55990) mediates 2-O- and 3-O-acetylation of xylosyl residues in xylan []. Its role is essential for the production of functional xylem vessels [, ]. It functions as a negative regulator of cold acclimation, and mutations in the ESK1 gene provides strong freezing tolerance []. | Short Name: | TBL28/TBL30/ESK1 |
