Placental alkaline phosphatase as the placental IgG receptor.
We review data from our studies of the physiological role of placental alkaline phosphatase (PLAP) and report that, in addition to functioning in catalysis, PLAP has the capacity to bind the Fc portion of human IgG. The dissociation constant for the interaction (3.86 mumol/L) indicates that the PLAP-IgG complex probably occurs in vivo. Furthermore, the electrophoretic and immunochemical propert...
متن کاملNucleotide and amino acid sequences of human intestinal alkaline phosphatase: close homology to placental alkaline phosphatase.
A cDNA clone for human adult intestinal alkaline phosphatase (ALP) [orthophosphoric-monoester phosphohydrolase (alkaline optimum); EC 3.1.3.1] was isolated from a lambda gt11 expression library. The cDNA insert of this clone is 2513 base pairs in length and contains an open reading frame that encodes a 528-amino acid polypeptide. This deduced polypeptide contains the first 40 amino acids of hum...
متن کاملCharacterization of KB cell alkaline phosphatase. Evidence of similarity to placental alkaline phosphatase.
The alkaline phosphatase from KB cells was purified, characterized, and compared to placental alkaline phosphatase, which it resembles immunologically. Two nonidentical nonomeric subunits of the KB phosphatase were found. The two subunits, which have apparent molecular weights of 64,000 and 72,000, can be separated on polyacrylamide gels containing sodium dodecyl sulfate. The Mr = 64,000 KB sub...
متن کاملMutation of a single amino acid converts germ cell alkaline phosphatase to placental alkaline phosphatase.
Human placental and germ cell alkaline phosphatases (PLAP and GCAP, respectively), are characterized by their differential sensitivities to inhibition by L-leucine, EDTA, and heat. Yet, they differ by only 7 amino acids at positions 15, 67, 68, 84, 241, 254, and 429 within their respective 484 residues. To determine the structural basis and the amino acid(s) involved in these physicochemical di...
متن کاملComparative Assessment of Ultrasound Placental Findings in Small for Gestational Age and Normal-Weight Fetuses
Background Small for gestational age (SGA) refers to newborns whose birth weight is less than the 10th percentile for gestational age. The aim of this study was to provide a comparative assessment of ultrasound placental findings in SGA and normal-weight fetuses in singleton pregnant women. Materials and Methods In...
