CC -!- FUNCTION: Probably plays an important role in the regulation of
CC erythrocyte shape and mechanical properties.
CC -!- SUBUNIT: Oligomer. Interacts with the cytoplasmic domain of SLC4A1/band
CC 3 anion transport protein.
CC -!- INTERACTION:
CC P16452; Q92876: KLK6; NbExp=3; IntAct=EBI-1182496, EBI-2432309;
CC P16452; P58062: SPINK7; NbExp=3; IntAct=EBI-1182496, EBI-1182445;
CC -!- SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor; Cytoplasmic side.
CC Cytoplasm, cytoskeleton. Note=Cytoplasmic surface of erythrocyte
CC membranes.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=Short;
CC IsoId=P16452-1; Sequence=Displayed;
CC Name=Long;
CC IsoId=P16452-2; Sequence=VSP_006416;
CC Name=3;
CC IsoId=P16452-3; Sequence=VSP_055340;
CC -!- PTM: Both cAMP-dependent kinase (CAPK) and another kinase present in
CC the red-blood cells seem to be able to phosphorylate EPB42.
CC {ECO:0000269|PubMed:8499466}.
CC -!- DISEASE: Spherocytosis 5 (SPH5) [MIM:612690]: Spherocytosis is a
CC hematologic disorder leading to chronic hemolytic anemia and
CC characterized by numerous abnormally shaped erythrocytes which are
CC generally spheroidal. Absence of band 4.2 associated with spur or
CC target erythrocytes has also been reported.
CC {ECO:0000269|PubMed:10406914, ECO:0000269|PubMed:1558976,
CC ECO:0000269|PubMed:7772513, ECO:0000269|PubMed:7819064,
CC ECO:0000269|PubMed:8547071, ECO:0000269|PubMed:8547605}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
CC -!- MISCELLANEOUS: The substitution of an Ala for a Cys in the active site
CC may be responsible for the lack of transglutaminase activity of band
CC 4.2.
CC -!- MISCELLANEOUS: [Isoform Short]: Major isoform.
CC -!- SIMILARITY: Belongs to the transglutaminase superfamily.
CC Transglutaminase family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAA36401.1; Type=Frameshift; Evidence={ECO:0000305};
