This gene encodes a member of the membrane-spanning 4A
gene family. Members of this 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. This family member
likely plays a role in signal transduction and may function as a
subunit associated with receptor complexes. The gene encoding this
protein is localized to 11q12, among a cluster of related family
members. Alternative splicing may result in multiple transcript
variants; however, not all variants have been fully described.
