Summary: Predicted to enable cytokine activity and transforming growth factor beta receptor binding activity. Involved in several processes, including cellular response to cGMP; regulation of gene expression; and response to bacterium. Located in extracellular space. Is expressed in coelomocyte; neurons; pharynx; and in male. Human ortholog(s) of this gene implicated in myostatin-related muscle hypertrophy and vertebral hypersegmentation and orofacial anomalies. Orthologous to several human genes including GDF11 (growth differentiation factor 11). [provided by Alliance of Genome Resources, Dec 2024]

DAF-7, which is secreted in part from a specific pair of ciliated neurons, acts as a systemic factor that activates a canonical TGFbeta signaling pathway in distant tissues to induce autophagy

blmp-1 is necessary for controlling histone methylation level in daf-7 mutants, suggesting BLMP-1 regulates the expression of SAMS-1, which in turn may regulate histone methylation and dauer formation.Our results reveal a new interaction between BLMP-1/BLIMP-1 and LIN-40/MTA1, as well as potential epigenetic downstream pathways
Title: BLIMP-1/BLMP-1 and Metastasis-Associated Protein Regulate Stress Resistant Development in Caenorhabditis elegans.
DAF-7 expression decreases as animals age during adulthood. Age-dependent diminished expression contributes to the reduced sensitivity of aging animals to the effects of dietary restriction.
Title: Age-Dependent Neuroendocrine Signaling from Sensory Neurons Modulates the Effect of Dietary Restriction on Longevity of Caenorhabditis elegans.
Using functional, fluorescently-tagged protein, we find that, in animals with mutant DAF-28/IGF, the wild-type DAF-7/TGF-beta is mislocalized to and accumulates in the proximal axon of the ASI neuron. Activation of two different branches of the unfolded protein response can modulate both the developmental phenotype and DAF-7 mislocalization in DAF-28(R37C) animals, but appear to act through divergent mechanisms

A gene-expression-based neural code for food abundance that modulates lifespan includes daf-7 that primarily regulates gene-expression variability, while tph-1 primarily regulates the dynamic range of gene-expression responses.
