• Protein processing & maturation
• Signaling (Hedgehog, GPCRs, ion channels)

Function

A subset of these microexons is included exclusively in photoreceptor transcripts, particularly in genes involved in cilia biogenesis and vesicle-mediated transport and this microexon program is regulated by Srrm3, a paralog of the neural microexon regulator Srrm4. Despite the fact that both proteins positively regulate reti microexons in vitro, only Srrm3 is highly expressed in mature photoreceptors ( 35858306).
