Summary
LMO2 encodes a cysteine-rich, two LIM-domain protein that is required for yolk sac erythropoiesis. The LMO2 protein has a central and crucial role in hematopoietic development and is highly conserved. The LMO2 transcription start site is located approximately 25 kb downstream from the 11p13 T-cell translocation cluster (11p13 ttc), where a number T-cell acute lymphoblastic leukemia-specific translocations occur. Alternative splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Nov 2008]

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.

    See identical proteins and their annotated locations for NP_001135787.1

    Status: REVIEWED

    Description
    Transcript Variant: This variant (2) differs in the 5' UTR and lacks a portion of the 5' coding region, compared to variant 1. These differences cause translation initiation at a downstream in-frame ATG and an isoform (2) with a shorter N-terminus, compared to isoform 1. Variants 2 and 3 encode the same isoform (2).

    Description
    Transcript Variant: This variant (3) differs in the 5' UTR and has an additional segment downstream of the 5' coding region, compared to variant 1. These differences cause translation initiation at a downstream in-frame ATG and an isoform (2) with a shorter N-terminus, compared to isoform 1. Variants 2 and 3 encode the same isoform (2).
