Sequence Name

C37E2.5  

WB ID

Description

ceh-37 encodes one of three C. elegans proteins with an OTX-like homeodomain; however, CEH-37 lacks other domains found in OTX proteins, and the CEH-37 homeodomain is predicted to resemble the Myb domain of telomere-binding proteins; CEH-37 binds the telomeric sequence 'TTAGGC' if it is repeated at least 1.5 times, and is mainly localized to the telomere in vivo; ceh-37 mutants have a weak increase in chromosomal nondisjunction; CEH-37 is involved in specifying some aspects of the AWB olfactory neuron fate, such as expression of an AWB-specific odorant receptor and a LIM-class homeodomain protein, LIM-4; CEH-37 is expressed broadly in the early embryo, while in larvae and adults it is expressed solely in the excretory cell.
