1. A method of inserting a polynucleotide sequence into a genome of a human pluripotent stem cell, comprising:
- simultaneously introducing into the human pluripotent stem cell;
a circular nucleic acid comprising the polynucleotide sequence flanked by a phiC31 first recombination site and a Bxb1 first recombination site;
a phiC31 integrase; and
a Bxb1 integrase,wherein the human pluripotent stem cell comprises a phiC31 second recombination site and a Bxb1 second recombination site at H11 locus in chromosome 22;
maintaining the human pluripotent stem cell under conditions that facilitate simultaneous recombination between phiC31 first recombination and phiC31 second recombination sites and between the Bxb1 first recombination and Bxb1 second recombination sites,wherein the introducing and maintaining results in insertion of the polynucleotide sequence into the genome of the human pluripotent stem cell at the H11 locus an expression of a product of the polynucleotide sequence.

Abstract
Methods for inserting a polynucleotide sequence into the genome of a human cell are provided. The present methods result in insertion of a polynucleotide sequence of interest into the H11 locus in the genome of a human cell. Also provided are nucleic acids that include sequences for integrating a polynucleotide sequence of interest into the H11 locus in the genome of a human cell. A transgenic human cell including site specific recombination sites at the H11 locus is also disclosed.
