Motif enrichment analysis

Motif	Selected genes from Max1∼4 clustera,b	Ribosomal proteins in Max1∼4 clustera,c	Total of 1257 genes with mRNA profiles
GCCCTAA	14 (3.84 × 10−9)	16 (1.07 × 10−9)	55
G/CCCCT/CAA	26 (4.17 × 10−3)	34 (8.85 × 10−4)	414

P-values for enrichment of strict and degenerated motifs according to fisher's exact test were shown in parentheses.

^aThere were 211 genes that belong to Max1∼4 cluster.

^bThirty-seven genes were evaluated (see Materials and Methods).

^cForty-eight genes are annotated as (putative) ribosomal protein genes out of 211 genes in the Max1∼4 cluster.
