CC   -!- FUNCTION: May dephosphorylate receptor tyrosine-protein kinase
CC       ERBB4 and inhibits its ligand-induced proteolytic cleavage
CC       (PubMed:15219672). May play a role in odontogenesis
CC       (PubMed:27843125). {ECO:0000269|PubMed:15219672,
CC       ECO:0000269|PubMed:27843125}.
CC   -!- CATALYTIC ACTIVITY: A phosphate monoester + H(2)O = an alcohol +
CC       phosphate.
CC   -!- SUBUNIT: Homodimer. {ECO:0000305|PubMed:15219672}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass type I
CC       membrane protein {ECO:0000255}.
CC   -!- ALTERNATIVE PRODUCTS:
CC       Event=Alternative splicing; Named isoforms=3;
CC       Name=1;
CC         IsoId=Q9BZG2-1; Sequence=Displayed;
CC       Name=2; Synonyms=Variant 3;

CC       Name=3; Synonyms=Truncated variant 1, Truncated variant 2;
CC         IsoId=Q9BZG2-3; Sequence=VSP_021493, VSP_021495;
CC   -!- TISSUE SPECIFICITY: Expressed mainly in the testis. Also expressed
CC       in the brain where they are enriched at the postsynaptic sites.
CC       Expressed at lower levels in the trachea, prostate, bone marrow,
CC       spinal cord, colon, fetal brain, heart, thymus, fetal liver,
CC       spleen, leukocytes, ovary, small intestine, pancreas and skeletal
CC       muscle. Expression is significantly lower in testicular cancer
CC       tissues than in normal testicular tissues. Isoform 3 is expressed
CC       in the testis, trachea, prostate and bone marrow.
CC       {ECO:0000269|PubMed:11414767}.
CC   -!- INDUCTION: Up-regulated by mibolerone (a synthetic androgen) and
CC       dihydrotestosterone (DHT) and is down-regulated by estrogen and
CC       progestin. {ECO:0000269|PubMed:11414767}.
CC   -!- PTM: Glycosylated. {ECO:0000305|PubMed:15219672}.
CC   -!- DISEASE: Amelogenesis imperfecta 1J (AI1J) [MIM:617297]: A form of
CC       amelogenesis imperfecta, a disorder characterized by defective
CC       enamel formation. The enamel may be hypoplastic, hypomineralized
CC       or both, and affected teeth may be discoloured, sensitive or prone
CC       to disintegration. AI1J is an autosomal recessive form
CC       characterized by hypoplastic enamel, enamel discolorization
CC       ranging from yellow to black, and normal dentin.
CC       {ECO:0000269|PubMed:27843125}. Note=The disease is caused by
CC       mutations affecting the gene represented in this entry.
CC   -!- SIMILARITY: Belongs to the histidine acid phosphatase family.
