Protein attributes

Sequence length	156 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	May be involved in gene regulation within neural lineage cells potentially by direct DNA binding or by binding to other transcription factors. Ref.3
Subcellular location	Nucleus By similarity.
Tissue specificity	Expressed mainly in the central nervous. Low level of expression in other tissues including thymus. Ref.7
Involvement in disease	A chromosomal aberration involving LMO1 may be a cause of a form of T-cell acute lymphoblastic leukemia (T-ALL). Translocation t(11,14)(p15;q11) with TCRD.
Sequence similarities	Contains 2 LIM zinc-binding domains.
