ph-d | Polyhomeotic distal (ph-d) encodes a stoichiometric subunit of the Polycomb repressive complex 1. The complex silences a variety of genes involved in developmental patterning, regulation of cell proliferation, differentiation and polarity. Together with its paralog ph-p, ph-d functions as a tumor suppressor gene. (1537 aa) | ||||
Hel25E | ATP-dependent RNA helicase WM6; Required for mRNA export out of the nucleus. Probable RNA helicase that may regulate entry into mitosis by down-regulating the expression of other genes whose activity may be rate-limiting for entry into mitosis during embryogenesis. Binds to salivary gland chromosomes and modifies position effect variegation. Promotes an open chromatin structure that favors transcription during development by regulating the spread of heterochromatin. (424 aa) |
