Pathway (FlyBase)
Positive Regulators of Notch Signaling Pathway -
The Notch receptor signaling pathway is activated by the binding of the transmembrane receptor Notch (N) to transmembrane ligands, Dl or Ser, presented on adjacent cells. This results in the proteolytic cleavage of N, releasing the intracellular domain (NICD). NICD translocates into the nucleus, interacting with Su(H) and mam to form a transcription complex, which up-regulates transcription of Notch-responsive genes. Positive regulators of the pathway enhance the signal from the sending cell or the response in the receiving cell. (Adapted from FBrf0225731 and FBrf0192604).
Protein Function (UniProtKB)
Involved in the control of cell fates in the neurectoderm. Acts as a positive regulator of Notch pathway and is required at different levels during development.
(UniProt, Q9U4H5)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
amx: almondex
Eyes slightly reduced, narrower below. Trident pattern stronger than in lz. Maternal effect lethal. Studies by Shannon [1972, Genetica (The Hague) 43: 244-56] show that amx progeny and many amx/+ progeny of amx mothers are embryonic lethals. Ovaries and egg production of amx females normal. General disorganization of early embryo with amx/+ progeny of amx mothers less extreme than amx progeny (Shannon, 1973, J. Exp. Zool. 183: 383-400); amx/+ daughters show 0.2% survival; amx/Dp(1;1)lz-2 show considerably higher survival (Campos-Ortega); Lethal embryos exhibit hypertrophy of central nervous system at the expense of epidermal tissue (Lehmann, Dietrich, Jimenez, and Campos-Ortega, 1981, Wilhelm Roux's Arch. Dev. Biol. 190: 226-29; Lehmann, Jimenez, Dietrich, and Campos-Ortega, 1983, Wilhelm Roux's Arch. Dev. Biol. 192: 62-74). Similarly peripheral nervous elements, the sensilla, exhibit increased numbers and abnormal morphology; cells diverted from epidermal to neurological pathway (Hartenstein and Campos-Ortega, 1986, Wilhelm Roux's Arch. Dev. Biol. 195: 210-21). Embryonic phenotype locally rescuable by injections of ooplasm from wild-type or pcx ova during preblastoderm stages (Campos-Ortega, La Bonne and Mahowald, 1985, Dev. Biol. 110: 264-67). lz/amx is wild type. Mosaics in amx/+ daughters of _/_ or amx/+ females show that ventral tissues are sensitive to reduced amx+ activity; no clones of amx tissue found in cuticle of amx/+ daughters of amx mothers (Germeraad and Disano, 1984, Genetics 107: s36).

        Other Comments

        amx is a neurogenic gene required initially to ensure the correct number of PNS precursors. amx is not required for the late epidermal maintenance function.

        (Bodmer et al., 1993)

        amx is needed for proper mesoderm differentiation prior to the onset of nau expression.

        (Corbin et al., 1991)

        Mutant alleles cause hypertrophy in nau expressing cells.

        (Corbin et al., 1991)

        Ecol\lacZ reporter gene constructs demonstrate that amx is required to restrict the number of competent cells that will become sensory mother cells, SMCs.

        (Goriely et al., 1991)

        Increasing the number of wild type copies of amx does not modify the bib mutant phenotype.

        (de la Concha et al., 1988)

        Normal amx function is required during zygotic development for the normal development of the eye and during oogenesis for the synthesis of a maternal component required for neurogenesis and mesoderm diffentiation.
