This gene encodes a member of the membrane-spanning 4A
gene family. Members of this nascent protein family are
characterized by common structural features and similar intron/exon
splice boundaries and display unique expression patterns among
hematopoietic cells and nonlymphoid tissues. The gene encoding this
protein is localized to 11q12.1, among a cluster of family members.
Alternative splicing of this gene results in several transcript
variants.
