Annotated Information
Name
DSCR8：Down syndrome critical region 8 (non-protein coding)
MMA-1a：malignant melanoma-associated 1;MMA-1b:a splice variant of MMA-1a[1]
Characteristics
MMA-1a is localized on chromosome 21q22.2, adjacent to the genes DSCR4 and KCNJ15.[1]
The MMA-1a gene consists of 4 exons, separated by 3 introns, of which intron 2 is extremely large. A further homology search displayed another human EST, identical to MMA-1a, but missing exon 3, was named MMA-1b. The MMA-1a and MMA-1b transcripts contain an open reading frame (ORF) coding for proteins of 91 and 37 amino acids, respectively.[1]
Function
The integration or lack of exon 3 in MMA-1a or MMA-1b transcripts might influence the structure of the putative proteins such that it regulates their involvement in carcinogenesis.[1]
Disease
Expression
MMA-1a and MMA-1b are predominantly expressed in the testis; although expression is less extensive, MMA-1b seems also considerably expressed in the placenta. In some other normal tissues, MMA-1a and/or MMA-1b expression is very low. Generally, in both tumor lesions and tumor cell lines, when MMA-1a is expressed, expression of MMA-1b could also be detected. On the other hand, MMA-1b is expressed more frequently and could be detected without expression of MMA-1a, especially after semi-nested PCR.[1]
