The molecular biology of metazoan eye development is an area of intense
investigation. These efforts have led to the surprising recognition that although
insect and vertebrate eyes have dramatically different structures, the orthologs
or family members of several conserved transcription and signaling regulators
such as Pax6, Six3, Prox1, and Bmp4 are commonly required for their development.
In contrast, our understanding of posttranscriptional regulation in eye
development and disease, particularly regarding the function of RNA-binding
proteins (RBPs), is limited. We examine the present knowledge of RBPs in eye
development in the insect model Drosophila as well as several vertebrate models
such as fish, frog, chicken, and mouse. Interestingly, of the 42 RBPs that have
been investigated for their expression or function in vertebrate eye development,
24 (~60%) are recognized in eukaryotic cells as components of RNA granules such
as processing bodies, stress granules, or other specialized ribonucleoprotein
(RNP) complexes. We discuss the distinct developmental and cellular events that
may necessitate potential RBP/RNA granule-associated RNA regulon models to
facilitate posttranscriptional control of gene expression in eye morphogenesis.
In support of these hypotheses, three RBPs and RNP/RNA granule components Tdrd7,
Caprin2, and Stau2 are linked to ocular developmental defects such as congenital
cataract, Peters anomaly, and microphthalmia in human patients or animal models.
We conclude by discussing the utility of interdisciplinary approaches such as the
bioinformatics tool iSyTE (integrated Systems Tool for Eye gene discovery) to
prioritize RBPs for deriving posttranscriptional regulatory networks in eye
development and disease. WIREs RNA 2016, 7:527-557. doi: 10.1002/wrna.1355 For
