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. [provided by RefSeq, Jul 2008],

Function:
Caution:The sequence shown here is derived from an Ensembl automatic analysis pipeline and should be considered as preliminary data.,Domain:The C-terminal region is required for binding to CDKN3-CDK2 complexes and the modulation of CDKN3 activity.,Function:Hematopoietic modulator for the G1-S cell cycle transition. Modulates the level of phosphorylation of cyclin-dependent kinase 2 (CDK2) through its direct binding to cyclin-dependent kinase inhibitor 3 (CDKN3/KAP).,similarity:Belongs to the MS4A family.,subcellular location:Located in the perinuclear area.,subunit:Interacts with CDKN3. Interacts with CDKN3-CDK2 complexes through its binding to CDKN3; this interaction facilitates dissociation of cyclin A from CDKN3-CDK2 complexes.,tissue specificity:Expressed specifically in hematopoietic cells and tissues.,
