UniProtKB - Q9XIA9 (LACS2_ARATH)
Protein
Long chain acyl-CoA synthetase 2
Gene
LACS2
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Activation of long-chain fatty acids for both synthesis of cellular lipids, and degradation via beta-oxidation. Acts in the cutin pathway. Preferentially uses palmitate, palmitoleate, oleate and linoleate. Required for repression of lateral root formation through its role in cutin biosynthesis and subsequent aerial tissues permeability.

Expressioni
Tissue specificityi
Expressed along the entire length of the stem, but expression was not entirely epidermal specific, with some expression found in internal cell layers as well. Was expressed in leave epidermal cells, flowers (sepals, petals, stamens, filaments and carpel), siliques and developing seeds. In roots, expression was detected in an internal cell layer, probably the endodermal layer.2 Publications
