Genes affected

ADAMTSL4-AS1 (HGNC:32041): (ADAMTSL4 antisense RNA 1)

ADAMTSL4-AS1 links:

MCL1 (HGNC:6943): (MCL1 apoptosis regulator, BCL2 family member) This gene encodes an anti-apoptotic protein, which is a member of the Bcl-2 family. Alternative splicing results in multiple transcript variants. The longest gene product (isoform 1) enhances cell survival by inhibiting apoptosis while the alternatively spliced shorter gene products (isoform 2 and isoform 3) promote apoptosis and are death-inducing.

MCL1 links:

ADAMTSL4 (HGNC:19706): (ADAMTS like 4) This gene is a member of ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs)-like gene family and encodes a protein with seven thrombospondin type 1 repeats. The thrombospondin type 1 repeat domain is found in many proteins with diverse biological functions including cellular adhesion, angiogenesis, and patterning of the developing nervous system. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Sep 2014]
