Abstract

Purpose : Our recent studies have shown that SUMO1 and SUMO2/3 have distinct functions in regulating lens differentiation (Gong et al. 2014 PNAS). To further explore the functions of sumoylation in othee tissues of the vertebrate eye, here we have characterized the expression patterns of different SUMO isoforms in these tissues.

Methods : QRT-PCR, Immunocytochemistry and Western blot analysis were used for the detection of SUMO isoform expression patterns.

Results : Compared with SUMO2/3, SUMO1 is highly expressed in the cornea, retina and lens epithelial cells. The number of proteins conjugated by SUMO1 is: retina>lens epithelial cells>cornea>Lens fiber cells. Unconjugated SUMO isoforms are hardly detected in C57 mice.

Conclusions : SUMO isoforms differentially conjugated to various proteins in retina, lens and cornea. Sumoylation may play an important role in different tissues of the vertebrate eye.
