Predicted to enable DNA binding activity; enzyme binding activity; and histone binding activity. Predicted to contribute to 3'-5' DNA helicase activity and single-stranded DNA helicase activity. Predicted to be involved in several processes, including DNA-dependent DNA replication; cochlea development; and double-strand break repair via break-induced replication. Predicted to act upstream of or within cellular response to interleukin-4 and nucleosome assembly. Located in nucleus. Human ortholog(s) of this gene implicated in Alzheimer's disease and autosomal dominant nonsyndromic deafness 70. Orthologous to human MCM2 (minichromosome maintenance complex component 2).
