set-4 encodes a putative histone H4 lysine-20 methyltransferase; SET-4 is orthologous to Drosophila SUV4-20, and to human SUV420H1 (OMIM:610881) and SUV420H2; set-4(RNAi) animals exhibit an extended adult fertile worm lifespan.
Predicted to enable histone H4K20me methyltransferase activity. Involved in determination of adult lifespan. Predicted to be located in chromosome and nucleus. Expressed in several structures, including hypodermis and muscle cell. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 51. Is an ortholog of human KMT5B (lysine methyltransferase 5B) and KMT5C (lysine methyltransferase 5C).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
