MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the SNF subfamily of helicase proteins. The encoded protein plays a critical role in the restoration of heterochromatin organization and propagation of epigenetic patterns following DNA replication by mediating histone H3/H4 deacetylation. Mutations in this gene are associated with adermatoglyphia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011] PHENOTYPE: Homozygotes for a targeted null mutation exhibit retarded growth, impaired fertility, skeletal dysplasias, and peri- and postnatal lethality. Mutant phenotypes are influenced by genetic background. [provided by MGI curators]

Nature of Mutation |
DNA sequencing using the SOLiD technique identified a T to A transversion at position 1375 of the Smarcad1 transcript, in exon 9 of 24 total exons. The mutated nucleotide causes a phenylalanine to isoleucine substitution at amino acid 344 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
|
Protein Function and Prediction |
Smarcad1 encodes a 1021 amino acid ATP-dependent DNA helicase. The SMARCAD1 protein contains two CUE domains at residues 156-198 and 247-290 that may be involved in binding ubiquitin-conjugating enzymes, an ATP-binding helicase domain at amino acids 504-672, a C-terminal helicase domain with a DEAD box motif at residues 853-1005, and a nuclear localization signal at amino acids 716-733. The protein is phosphorylated on multiple residues (Uniprot Q04602). Homozygotes for a targeted null mutation exhibit retarded growth, impaired fertility, skeletal dysplasias, and peri- and postnatal lethality. Mutant phenotypes are influenced by genetic background.
The F344I change does not occur in any of the SMARCAD1 domains, and is predicted to be possibly damaging by the PolyPhen program.
