Podbilewicz B. ADM-1, a protein with metalloprotease- and disintegrin-like domains, is expressed in syncytial organs, sperm, and sheath cells of sensory organs in Caenorhabditis elegans. Mol Biol Cell. 1996;7:1877-93 pubmed
..ADM-1 expression in the hypodermis, pharynx, vulva, and mature sperm is consistent with a putative role in somatic and gamete cell fusions. ..
Shemer G, Suissa M, Kolotuev I, Nguyen K, Hall D, Podbilewicz B. EFF-1 is sufficient to initiate and execute tissue-specific cell fusion in C. elegans. Curr Biol. 2004;14:1587-91 pubmed
..Surprisingly, eff-1 is not required to fuse the gonadal anchor cell to uterine cells. Thus, eff-1 is sufficient and essential for most but not all cell fusion events during C. elegans development. ..

. The C. elegans developmental fusogen EFF-1 mediates homotypic fusion in heterologous cells and in vivo. Dev Cell. 2006;11:471-81 pubmed
..Thus, although EFF-1-mediated fusion shares characteristics with viral and intracellular fusion, including an apparent hemifusion step, it differs from these reactions in the homotypic organization of the fusion machinery. ..

. Genetic control of fusion pore expansion in the epidermis of Caenorhabditis elegans. Mol Biol Cell. 2007;18:1153-66 pubmed
..The first cell fusion does not trigger a wave of orderly fusions in either direction. Ultrastructural studies show that epidermal syncytiogenesis require eff-1 activities to initiate and expand membrane merger...

. AFF-1, a FOS-1-regulated fusogen, mediates fusion of the anchor cell in C. elegans. Dev Cell. 2007;12:683-98 pubmed
..Thus, FOS-1 links cell invasion and fusion in a developmental cascade. ..
Oren Suissa M, Hall D, Treinin M, Shemer G, Podbilewicz B. The fusogen EFF-1 controls sculpting of mechanosensory dendrites. Science. 2010;328:1285-8 pubmed publisher
..Neuronal pruning appeared to involve EFF-1-dependent branch retraction and neurite-neurite autofusion. Thus, EFF-1 activities may act as a quality control mechanism during the sculpting of dendritic trees...

. Conserved eukaryotic fusogens can fuse viral envelopes to cells. Science. 2011;332:589-92 pubmed publisher
..Thus, FF proteins are part of an ancient family of cellular fusogens that can promote fusion when expressed on a viral particle. ..

Smurova K, Podbilewicz B. RAB-5- and DYNAMIN-1-Mediated Endocytosis of EFF-1 Fusogen Controls Cell-Cell Fusion. Cell Rep. 2016;14:1517-1527 pubmed publisher
..Downregulation of dynamin or RAB-5 caused EFF-1 mislocalization to all apical membrane domains and excessive fusion. Thus, internalization of EFF-1 is a safety mechanism preventing excessive cell fusion. ..
