Summary
[Wormbase] her-1 generates two transcripts, the larger of which encodes a small, secreted, cysteine-rich protein (HER-1A) required for normal sex determination in wild-type XO male animals, while being dispensable for sex determination in XX hermaphrodites; transcription of her-1 in XX animals is repressed by SDC-2; HER-1A protein has two all-helical domains, with fourteen conserved cysteine residues forming seven disulfide bonds, at least eight of which residues are critical for function in vivo; HER-1A has no known homologs except in other nematodes (e.g., Brugia malayi), and does not structurally resemble other well-known secreted proteins; HER-1A inhibits the receptor TRA-2A in vivo, and binds it in vitro; HER-1A functions nonautonomously and requires a signal sequence for biological activity; the her-1(n695gf) mutation alters a site in the her-1 promoter bound by SDC-2, partially transforms XX animals into phenotypic males, and requires sup-26 and sup-27 to do so
.
Wormbase predicts 2 models.

The spliced mRNA putatively encodes
a good protein, altogether
2 different isoforms (2 COOH complete), some containing Protein of unknown function Her-1
domain [Pfam].
Function: There are

Legend
Introns are depicted by broken lines; the height of the top of each intron reflects the relative number of clones supporting this intron.
]^[ A pink broken line denotes an intron with standard boundaries (gt-ag or gc-ag) that is exactly supported (i.e. a cDNA sequence exactly matches the genome over 16 bp, 8 on both sides of the intron).
] ^ ] A blue broken line denotes non-standard introns, exactly supported, but with non-standard at-ac or any other boundaries.
]-[ Pink and
] - ] blue straight lines represent 'fuzzy' introns of the standard and non-standard types respectively, those introns do not follow the 16 bp rule. Black straight lines ]-[denote gaps in the alignments.
Exons: Wide filled pink areas represent putative protein coding regions, narrow empty pink boxes represent the 5'UTR (on the left) and 3' UTR (on the right). Flags identify validated endings: cap site on the 5' side, polyadenylation site on the 3' side. Filled flags correspond to frequent events while empty flags have lesser supporting cDNAs (yet all are validated); at the 3' side, black flags are associated to the main AATAAA signal,
blue flags to any single letter variant of the main . More explanations are given in the
