InterPro domain: IPR029985

Trichome birefringence-like (TBL) proteins are proposed to encode wall poly-saccharide specific O-acetyltransferases based on the existing data for some members of the TBL family: altered xyloglucan 4 (AXY4/TBL270) and altered xyloglucan 4-like (AXY4L/TBL22), two xyloglucan specific O-acetyltransferases in non-seed tissues and seeds, respectively [ 1 , 2 ].

This entry represent a group of TBL proteins that includes TBL25 and TBL26.
