Phosphatidylinositol transfer protein beta isoform is a protein that in humans is encoded by the PITPNB gene.{{cite journal | vauthors = Dunham I, Shimizu N, Roe BA, Chissoe S, Hunt AR, Collins JE, Bruskiewich R, Beare DM, Clamp M, Smink LJ, Ainscough R, Almeida JP, Babbage A, Bagguley C, Bailey J, Barlow K, Bates KN, Beasley O, Bird CP, Blakey S, Bridgeman AM, Buck D, Burgess J, Burrill WD, O'Brien KP| title = The DNA sequence of human chromosome 22 | journal = Nature | volume = 402 | issue = 6761 | pages = 489–95 |date=Dec 1999 | pmid = 10591208 | doi = 10.1038/990031 | bibcode = 1999Natur.402..489D |display-authors=etal| doi-access = free }}{{cite web | title = Entrez Gene: PITPNB phosphatidylinositol transfer protein, beta| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=23760}}

The protein encoded by this gene is found in the cytoplasm, where it catalyzes the transfer of phosphatidylinositol and phosphatidylcholine between membranes.
