SEPT5 (septin 5)


Other nameshCDCRel-1 (human cell division cycle regulation 1)
PNUTL1 (peanut (drosophila)- like 1)
AF22 (ALL1 fused gene from chromosome 22)
LocusID (NCBI) 5413
Atlas_Id 220
Location 22q11.21
Location_base_pair Starts at 19705958 and ends at 19710845 bp from pter ( according to hg19-Feb_2009)  [Mapping]

Description the gene spans 13 kb; 13 exons; one large intron (3.7kb) between exons 2 and 3
Transcription two major splicings in 5' (exons 1 and 2 versus exon 3; 2032 bp mRNA; coding sequence: 1109 bp; the gene is just 5'of GPIb beta (platelet membrane glycoprotein Ib beta precursor), and GPIb beta is co-expressed with hCDCRel-1; this is due to a non-consensus polyadenylation signal in 3' of hCDCRel-1


Description 369 amino acids; GTPase activity
Expression high level expression in brain, heart, platelets; low level expression in some other tissues
Localisation cytoplasm
Function see below; may have a role in the synaptic function of neurones in the brain
Homology belong to the septin family: filament forming proteins implicated in the cytoskeleton organization; nucleotide binding proteins; hCDCRel-1 is closely related to AF17q25/MSF, also found involved in fusion protein with MLL in leukemia

Implicated in

Entity t(11;22)(q23;q11) acute non lymphocytic leukemia (ANLL) --> MLL - hCDCRel-1
Disease M4, M2, and M1 ANLL
Hybrid/Mutated Gene 5' MLL - 3' hCDCRel, with fusion of MLL exon 7 to hCDCRel exon 3
Abnormal Protein NH2 - AT hook and DNA methyltransferase from MLL fused to hCDCREL-1 - COOH
