PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	two N-terminal LIM domains
	a conserved cysteine- and histidine-rich structure of two tandem repeated zinc fingers (LIM domain is involved in protein-protein interactions during transcriptional regulation)
	an homeodomain

secondary structure

HOMOLOGY

interspecies

homolog to rattus Isl2

FAMILY

CATEGORY

transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus

basic FUNCTION	transcription factor defining subclasses of motoneurons (that segregate into columns in the spinal cord and select distinct axon pathways)
	may be involved in both differentiation and maintenance of the tissues and might play an important role
	playing a prominent role in specifying retinal ganglion cell laterality
