ZNF75D Knockout cell line (HK-2)

Ubigene gene knockout cell lines mediated by optimized CRISPR-Cas9 technology provide reliable in vitro models for investigating gene function, signaling pathways, disease mechanisms, and therapeutic targets.

ZNF75D (zinc finger protein 75D) encodes a zinc finger protein containing an N-terminal SCAN domain, a KRAB box, and five C2H2-type zinc finger motifs. These structural features are characteristic of transcription factors involved in DNA binding and gene regulation. ZNF75D likely functions as a transcriptional regulator, although its specific molecular targets and biological roles remain incompletely characterized.

HK-2 (Human Kidney-2) is a well-characterized immortalized human kidney proximal tubular epithelial cell line derived from normal adult renal tissue. Transformed via the transduction of human papillomavirus type 16 (HPV-16) E6/E7 genes, HK-2 successfully achieves continuous in vitro proliferation while stably retaining the functional and phenotypic characteristics of primary proximal tubular epithelium. HK-2 cells maintain distinct brush border enzyme activities and exhibit physiologic responsiveness to cytokines and nephrotoxic compounds. Consequently, HK-2 serves as a globally accepted, standard human cell platform extensively utilized in in vitro nephrotoxicity screening, renal fibrosis modeling, tubular transport mechanism profiling, and preclinical drug safety evaluations.

Before delivery, each clone is authenticated by STR, tested for sterility and mycoplasma, and genotype‑verified by two‑round PCR‑sequencing. Comprehensive QC data accompany every shipment to support reproducible research.
