LIM domain transcription factor LMO4 is a protein that in humans is encoded by the LMO4 gene.^[3]

LIM domain only 4 is a cysteine-rich, two LIM domain-containing protein that may play a role as a transcriptional regulator or possibly an oncogene. Its mRNA is characterized by a GC-rich 5' region and by multiple ATTT motifs in the 3' region. A variant transcript missing a portion of the 5' region has been identified but cannot be confirmed because of the GC-rich nature of the region.^[3]

Interactions

LMO4 has been shown to interact with LDB1,^[4][5] RBBP8^[4][6] and BRCA1.^[4][6]
