Protein

Pleckstrin homology-like domain family A member 2

Gene

PHLDA2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Plays a role in regulating placenta growth. May act via its PH domain that competes with other PH domain-containing proteins, thereby preventing their binding to membrane lipids (By similarity).By similarity

Miscellaneous

The PHLDA2 locus is imprinted. Loss of imprinting results in overexpression. Imprinting is dependent on RNAi machinery.

Expressioni

Tissue specificityi

Expressed in placenta and adult prostate gland. In placenta, it is present in all cells of the villous cytotrophoblast. The protein is absent in cells from hydatidiform moles. Hydatidiform mole is a gestation characterized by abnormal development of both fetus and trophoblast. The majority of hydatidiform moles are associated with an excess of paternal to maternal genomes and are likely to result from the abnormal expression of imprinted genes (at protein level). Expressed at low levels in adult liver and lung, and fetal liver. Expressed in adult brain and neuroblastoma, medullablastoma and glioblastoma cell lines.5 Publications

Inductioni

Maternal PHLDA2 allele is activated, while paternal Phlda2 is repressed due to genomic imprinting. Down-regulated by hypoxia. Although highly similar to PHLDA3 protein, it is not regulated by p53/TP53.2 Publications

Domaini

The PH domain binds phosphoinositides with a broad specificity. It may compete with the PH domain of some other proteins, thereby interfering with their binding to phosphatidylinositol 4,5-bisphosphate (PIP2) and phosphatidylinositol 3,4,5-trisphosphate (PIP3) (By similarity).By similarity
