Summary
Enables chromatin binding activity. Contributes to DNA binding activity. Involved in negative regulation of erythrocyte differentiation. Acts upstream of or within embryonic hemopoiesis and positive regulation of transcription by RNA polymerase II. Located in nucleus. Part of protein-containing complex. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Used to study acute lymphoblastic leukemia. Orthologous to human LMO2 (LIM domain only 2). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) differs in the 5' UTR and 5' coding region, compared to variant 1. These differences allow translation initiation from an alternate start codon and an isoform (2) with a shorter and distinct N-terminus, compared to isoform 1.

    Description
    Transcript Variant: This variant (3) differs in the 5' UTR and 5' coding region, compared to variant 1. These differences cause translation initiation at an in-frame downstream ATG and an isoform (3) with a shorter N-terminus, compared to isoform 1. Variants 3 and 4 encode the same isoform (3).
