Handling procedures
Initial handling guidelines
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.
Subculture guidelines
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- Cells should be passaged when they have achieved 80-90% confluence.
Culture medium
DMEM (High Glucose) + 10% FBS
Cryopreservation medium
Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Biological function summary
G protein-coupled receptor kinase 4 regulates GPCR signaling by facilitating receptor internalization and degradation. This action modulates cellular responsiveness to hormones and neurotransmitters. GRK4 does not form part of a complex but its regulatory function directly impacts GPCR pathways. GRK4 achieves this control by adding phosphate groups typically functioning as a feedback mechanism during receptor activity.
Pathways
GRK4 serves as an important regulator in the MAPK signaling pathway and the renin-angiotensin-aldosterone system (RAAS). In MAPK pathways GRK4 helps mediate signal transduction by controlling receptor activity. It also interacts with other GRKs like GRK2 to fine-tune cellular responses and maintain homeostasis. Its involvement in RAAS highlights its significance in cardiovascular regulation.
