| KCNG4 | Potassium voltage-gated channel subfamily G member 4. Potassium channel subunit that does not form functional channels by itself. Can form functional heterotetrameric channels with KCNB1. Regulates ion transmembrane transport. |
| KIAA1549L | UPF0606 protein KIAA1549L. |
| KIR2DL1 KIR2DL1 | Killer cell immunoglobulin-like receptor 2DL1. Receptor on natural killer (NK) cells for some HLA-C alleles such as w4 and w6. Inhibits the activity of NK cells thus preventing cell lysis. |
| KIR2DL3 | Killer cell immunoglobulin-like receptor 2DL3. Receptor on natural killer (NK) cells for HLA-C alleles (HLA-Cw1, HLA-Cw3 and HLA-Cw7). Inhibits the activity of NK cells thus preventing cell lysis. |
| KIR2DS4 KIR2DS4 KIR2DS4 | Killer cell immunoglobulin-like receptor 2DS4. Receptor on natural killer (NK) cells for HLA-C alleles. Does not inhibit the activity of NK cells. |
| KRTAP10-6 | Keratin-associated protein 10-6. In the hair cortex, hair keratin intermediate filaments are embedded in an interfilamentous matrix, consisting of hair keratin-associated proteins (KRTAP), which are essential for the formation of a rigid and resistant hair shaft through their extensive disulfide bond cross-linking with abundant cysteine residues of hair keratins. |
| LCN12 | Epididymal-specific lipocalin-12. Binds all-trans retinoic acid and may act as a retinoid carrier protein within the epididymis. May play a role in male fertility (By similarity). |
| LDLRAD4 | Low-density lipoprotein receptor class A domain-containing protein 4. Functions as a negative regulator of TGF-beta signaling and thereby probably plays a role in cell proliferation, differentiation, apoptosis, motility, extracellular matrix production and immunosuppression. |
| LIPC | Hepatic triacylglycerol lipase. Hepatic lipase has the capacity to catalyze hydrolysis of phospholipids, mono-, di-, and triglycerides, and acyl-CoA thioesters. It is an important enzyme in HDL metabolism. |
| LPIN3 | Phosphatidate phosphatase LPIN3. Regulates fatty acid metabolism. Magnesium-dependent phosphatidate phosphatase enzyme which catalyzes the conversion of phosphatidic acid to diacylglycerol during triglyceride, phosphatidylcholine and phosphatidylethanolamine biosynthesis (By similarity). |
| MAML3 | Mastermind-like protein 3. Acts as a transcriptional coactivator for NOTCH proteins. Has been shown to amplify NOTCH-induced transcription of HES1. |
| MRGPRX1 | Mas-related G-protein coupled receptor member X1. Orphan receptor activated by neuropeptides terminating in Arg-Phe or Arg-Phe-amideMay regulate the function of nociceptive neurons by modulation of pain perception. |
| MST1L MST1L | Putative macrophage stimulating 1-like protein. |
| MUC4 MUC4 | Mucin-4. May play a role in tumor progression. Ability to promote tumor growth may be mainly due to repression of apoptosis as opposed to proliferation. Has anti-adhesive properties. |
| MYO1H | Unconventional myosin-Ih. Represents an unconventional myosin. |
| NBPF10 | Neuroblastoma breakpoint family member 10.. RNA binding. |
| NBPF12 NBPF12 | Neuroblastoma breakpoint family member 12. RNA binding. |
| NBPF20 | Neuroblastoma breakpoint family member 20. RNA binding. |
