Summary: Enables single-stranded RNA binding activity. Involved in several processes, including epithelial cell development; regulation of alternative mRNA splicing, via spliceosome; and regulation of neuron differentiation. Located in nuclear speck. Is expressed in several structures, including excretory cell; neurons; somatic nervous system; tail; and vulva. Orthologous to several human genes including ELAVL4 (ELAV like RNA binding protein 4).

What's a GeneRIF?

Interaction between mbl-1 and exc-7, double mutants displayed a severely shortened lifespan.
Title: CRISPR-mediated genetic interaction profiling identifies RNA binding proteins controlling metazoan fitness.
Here we combine RNA-seq with in vitro binding assays to study how 4 different C. elegans SFs, ASD-1, FOX-1, MEC-8, and EXC-7, regulate splicing. The 4 SFs chosen all have well-characterised biology and well-studied loss-of-function genetic alleles, and all contain RRM domains
Title: The combinatorial control of alternative splicing in C. elegans.
this study identifies two conserved RNA-binding proteins, UNC-75/CELF and EXC-7/Hu/ELAV, which regulate overlapping networks of splicing events in GABAergic and cholinergic neurons.
Title: A pair of RNA-binding proteins controls networks of splicing events contributing to specialization of neural cell types.
The subnuclear-localized EXC-7 protein acts in parallel to UNC-75 to affect cholinergic synaptic transmission.
Title: Two neuronal, nuclear-localized RNA binding proteins involved in synaptic transmission.
May affect expression of sma-1 and other genes to effect proper development of the excretory canals.
Title: The role of the ELAV homologue EXC-7 in the development of the Caenorhabditis elegans excretory canals.
