Description The gene spans 424 kb.on plus strand; at least 15 exons.
Transcription alternate splicing; at least 3 transcripts, of which are transcripts of 1,6 and 2,1 kb.


Description 328 amino acids, 35 kDa, and 251 amino acidsThe Musashi (Msi) family genes possess 2 ribonucleoprotein (RNP or ribonucleo particle)-type RNA recognition motifs (RRMs) in the N-term; each RRM comprises 2 highly conserved sequences called RNP1 and RNP2. Heterogeneous nuclear ribonucleoparticle (hnRNP) proteins are nuclear proteins implicated in hnRNA (pre-mRNA transcript) processing; Msi2 and Msi1 have similar RNA-binding specificity.
Expression Ubiquitously expressed in various tissues; expressed predominently in precursor cells in the ventricular zone and subventricular zone of the central nervous system (CNS); in CNS stem cells during embryogenesis; in the postnatal and adult CNS, the expression of Msi2 and Msi1 disappear in most post mitotic or migrating cells, but is found in cells of the astrocyte lineage; coexpressed with Msi1.
Function RNA-binding protein. Some RNA-binding proteins are neural-specific. The development of neural cells from precursors may be partly regulated at the post-transcriptional level by mRNA stabilization or translational control in the cytoplasm. Msi2 may have a unique role in CNS stem cells through life.
Homology MSI1


Germinal Defective MSI2 might play a role in certain dementia (although this chromosomal region also contain several loci known to be involved in neurological disorders ( NF1 and others).
